Hey mboltuzi,

Here's some advice I've got from Stardog regarding cooler height:

The Intel stock cooler will not fit. If you install a standard 9.5mm height 2.5" drive under the optical drive you have enough room for up to a 37mm tall cooler like the Silverstone NT07-1156. If using an SSD, you can creatively install it so the SSD is standing vertically which will give you a little more height to fit up to a 45mm tall cooler (stock Intel is 54mm if you're wondering).

And this is from eco

Whoops, somehow posted that the middle of typing.

Anyway, regarding the power supply this is from the E-i7 ecosmartpc page:
Quote:
The new 180W fanless DC power board and standard 84W AC adapter can power the latest Intel Celeron, Pentium or i3. Upgrade the AC adapter to 120W AC and there’s enough power for a Core i5 or Core i7 or 150W to support an AMD APU or Intel CPU with a low-profile graphics card.

I'm not planning to use optical drive anyway.  I'll buy some decent quiet cooler. :)

 

I have read ecosmartpc info but I would still like to hear some first-hand opinions. :)

I couldn't have said it any better than goodbyegalaxy smile.gif. Thanks!

All that information is from first-hand testing so rest assured. I will add that the 120W AC adapter is only $10 more than the 84W AC adapter so if you want a little future-proofing it's a good deal. Replacing it later will be more like $25-30.

I still like the Dynatron T450 for an inexpensive, quiet, easy to install low-profile cooler. It's 31mm high. If you want an extra cooling fan, the 80x15mm CoolerMaster fan works very well.

Hey guys. I am looking to build a powerfull (for the size) small machine, with the new pentium 20th anniversary edition and a gtx 750 ti. The gpu seems ideal for such a thing as it has loads of performance for a mere 60W...

I was looking at the Streacom F7C evo to house this, but it looks like the GPU would suffocate in there. The realan e-i7 looks like it has more space next to the pci-e slot... Could someone tell me if a dual slot gpu would fit in there? Or 1.5 slot?

You won't be able to fit a double-slot GPU in the E-i7. It's even a little smaller than the F7C. Even if you could, it would suffer from heat problems and the PSU would not be powerful enough.

Have you seen these mini-ITX cases? I get enough requests for something like yours that I was thinking of getting one and trying it out for offering a powerful HTPC/Gaming HTPC/PC with a serious GPU.

I have a powerful mini-itx build in a Fractal Node 304. It is half the size of my full desktop but a heck of a lot more powerful. It is still a small footprint and has enough breathing room to house a GTX780 and i7-4700k.

These mini-itx SFF builds intrigue me and I would need to get an i3 or celeron as my AMD APU is power hungry and needs sufficient cooling (A10-5800k) that I think being in this size of a build would cause some heat issues.

At least for the E-i3/E-i5/E-i7 if you have an Intel 65W TDP or less processor and an SSD, heat is not an issue. In the E-i7 if you want a GPU, something HD6670 or less with an extra 80mm fan or two is fine as well. If you're willing to throw some money at the cooling aspect, e.g. Noctua NH-L9i and some 80x15mm fans, it can work well, run cool/warm and still be quiet.

Stardog, it doesnt make much sense what you said that the e7 is even smaller than the f7c for the gpu... i mean its obvious from e pictures that it has more space next to the pci slot, after all it has those 2 positions to put 80mm fans there...
I mean it probably wont fit a dual slot gpu but at least 1.5 slot should be doable, or single slot along with a fan which would make it far from suffocating...
Am i missing something here?

I like the strecom much more on looks/quality and would probably wait for a true single slot low profile version of the gtx 750 ti to come out before doing this, but truth be told it seems much more spacious (as far as the gpu is concerned only) in the i7...

Thanks for the alternatives you showed me but those defeat the whole purpose of my project, they are too big. The point is building something very tiny that holds true power and not an onboard gpu...

The E-i7 will fit a low-profile, single slot GPU that doesn't require a power connector. If you can find a GPU that fits within those parameters and you're willing to experiment with cooling and throw some money at it, then it should work.

And, the dimensions of the E-i7 are smaller than the F7C.

My testing was done with a Sapphire LP HD6670 card and an i3-2120T CPU. Power draw was around 110W using Furmark. GPU temps were well into the 70sC with no fans. Adding an 80mm fan or two probably would have helped.

There might be a little room there for a fan that sticks out maybe 1/2 a slot but a full slot I don't see that working.

Hello,

I also would like to add an addition low profile single slot graphic card.
But I have currently the 84W version of this case and would like first to upgrade to have minimum 150W.

Do you think I should I buy the Realan powerboard LR1107 (180W input 12V) or LR1010 (180W input 17V-24V) ? I don't understand the difference, maybe the LR1010 can be used with standard laptop power AC-DC adapter ?
Which 150W AC-DC power adapter would be a good fit for this powerboard ?

I am living in Europe and usually have no problem ordering on Aliexpress.com.

Thanks in advance !

The difference is that one takes a 12V only input and the other allows for a input over a wider range. The 12V versions also tend to be cheaper, both the powerboard and the AC adapter. I would look at what 150W AC adapters are available to you locally, what their voltage is and then choose accordingly. You need a 2.5mm x 5.5mm tip for the AC adapter.

Ok I wanted to buy a Realan AC-DC power adapter, but it seems that they only provide 200W version, there is no 150W version :
http://www.minicase.net/product-power-adapter.html

Looks like I'll have to buy that power adapter somewhere else !

Thanks for the advice,

Hi Stardog
Really loving the look of this case.. I want to buy 2 of these case's the one without the drive slot, I am looking to put in the AMD Athlon 5350 (25watts) socket AM1 APUs on a MSI AM1L MB add to that a 64gb SSD

I live in the UK and can only find the early E-i7 case with the drive slot

Can you ship these to the UK or do you know where I can get this case from nearer to home

Unfortunately, the E-i7 without the ODD slot has long been sold out and the manufacturer isn't/won't make any more.

Thats a shame.... Thanks anyway
By the way whats your thoughts on the AMD AM1 APUs onboard R3 Radeon graphics vs a GeForce GT210/610 silent GPU is there enough power with these cases to run a dedicated GPU, The machine will be used for XBMC only

The integrated graphics should be enough but it depends entirely on what you're doing, what weird glitches you run into with your TV/AVR, media content, etc. I am using the 1st generation AMD APU (Llano) integrated graphics for my living room HTPC going through an Onkyo AVR to a Panasonic TV and it's great for live TV, SD DVDs and Blu-ray.

At the moment for my HTPC I'm using an AMD Phenom cpu with a GeForce GT440 and using a modified version of XBMC called DSPlayer where I'm implementing LAV Audio/Video filters... Now I'm trying to get the same performance I get now but with lower power and a smaller form factor,

Just to confirm can I put in a graphic if I feel its necessary

Yes, the E-i7 can take a low-profile single-slot GPU. I've tried with an HD5450 and HD6670 with no problems. The real limiting factor will be the power supply. The E-i7 on my site has a 12V 180W DC-DC powerboard so you can use up to a 180W AC-DC adapter with it. Most E-i7 from other vendors have the standard 12V 120V DC-DC powerboard.

Hi Stardog, hi all,

Although the posts on this thread stopped in 2014 I decided to have a try and post my experience here with the E-I7. I should say first that I do not have the Realan model since you cannot find this brand in East Europe but the same case licensed probably by a German company Inter-Tech.
So here it is my current build (2nd iteration):
- MB: Asrock H67M-ITX - it only takes Sandy and Ivy Bridge CPUs but has been rock solid until now, has 2 USB 3.0 ports, full PCIe 2.0 x16, 2 SATA 3 ports.
- CPU: Intel Core I3 3220T - max TDP 35W, dual core, 2.8 GHz, HD 2500 integrated (at the beginning I only wanted a low power CPU but a Core I not Celeron or Pentium since I really need the QSV in HandBrake to rip my blu-ray collection, and I did not pay attention to the integrated graphics too much ...)
- 2 x 4GB RAM ultra low profile Kingston
- PicoPSU 160xt + 192W external power brick (96W on the 12V line)
- 120 GB Intel 530 series SSD
- Noctua NH-L9i for the CPU
- dedicated GPU: Zotac GeForce GTX 750 TI, Low Profile
- 4 case fans: 2 Noctua NF-R8 redux-1200 (on the outside of the case as intake) and 2 Noctua NF-A8 ULN (on the inside of the case also as intake)
- ODD: Panasonic Blu-Ray RW UJ265

Initially I wanted to have 2 HDD 2.5 type in the case, a SSD for Win 8.1 and a 500 GB HDD as a place to store temporary files or install games. So I have taken a side by side mounting plate from an old case Antec ISK 100 and mount it below the ODD cage, the screws holding one of the HDD were also holding the plate so normally the other HDD was positioned next to it in the right part of the case looked from the front but this way there was no possibility anymore to mount a 2nd fan on the side.
One Noctua fan was mounted as intake on the rear right side of the case.
No dedicated GPU so far installed...

I was perfectly happy with the HTPCH I had until I have discovered madVR ... and things changed. I quickly realized that the integrated HD 2500 was not up to the task and since GTX 750 TI was already out and it only consumes 60W at load (no additional power connection) I decided to put one into the case. Normally I needed a LP one with 1 bracket - unfortunately there is no such thing out there until I have found the Zotac option somehow similiar the Galaxy one (very popular but difficult to find in Europe). It still has 2 brackets size with the heavy / bulky cooler but it only has 1 bracket shield and ... it does fit into the case.
Power was not an issue since the PicoPSU can deliver 96W on the 12V line which equals more or less the max TDP of the GPU: 60 W + max TDP of the CPU 35W. Of course there are also the fans, the SSD, the RAM and the MB itself but even in the most demanding games it's hard to hit the max TDP for both CPU and GPU.
But there was a problem ... heat and here come in the 4 Noctua fans. I decided to drop the 2 HDD option so that I could make some place for the 2nd fan on the right side, so mounted the 2 Noctua NF-A8 ULN to intake however I still felt that it was not enough. Consequently I have mounted also as intakes 2 Noctua NF-R8 redux-1200 on the outside of the case on the left side in front of the GPU exhaust holes.
In order to test the stability of the system I decided to run Prime95 4 threads (to occupy 100% the 4 threads of the CPU) and Furmark 4 MSAA.
The temps were measured for GPU with HWInfo, Zotac own tool and GPU-Z, for CPU with HWInfo, RealTemp and Asrock AXTU tool.
I left the 2 stress tools above run for approx. 1.5 hour and recorded the following results:
- power, no issue here, neither the CPU nor the GPU did not throttle because of lack of it (reminder: 5 fans were also spinning at their full speed...). No restart, no sudden shut-down, everything was still working during the 1.5 hrs stress test.
- thermal: GPU stabilized at 80C (my guess is that it was self throttling to avoid reaching higher temps), CPU cores varied between 67-70C. Temp in the romm was about 25-26C. I have also discovered with GPU-Z that the sweet spot for the GPU to not throttle is to keep the temp < 80C, even at 78C the Perf. CAP in GPU-Z was green, at 80C it turned purple showing problems.

Reading the first posts of this thread I have noticed that you advise to have the fans as exhaust. I'm going to try the following: leave the 2 outside fans in front of the GPU as intakes and reverse the inside fans as exhaust. Do you think this is the best solution?

Another option would be that on each side to have 1 fan as exhaust and 1 as intake. Would this work better than the above solution where the GPU would block somehow the intake flow?

Because this case is not a normal tower case where you put the intake fan at the down part of the case and the exhaust at the upper part of the case I really need some advise on the best solution for my case.

As a disclaimer, I don't have any experience using video cards in these cases. But in general with PCs you want to use your fans to direct the airflow on a path through the case, passing over all of the components that generate heat. If all of your fans are intakes, you probably aren't accomplishing that. If you put the intakes and exhausts right beside each other, you probably aren't accomplishing that either.

I can't picture exactly what you're describing, but intakes pointed at the GPU and exhausts on the opposite side of the case sounds like your best bet to me.

Ok thanks, got the point. This is what I was about to test first but I need to wait a little until I receive some fan guards for the exhaust fans. I was worried in this scenario that the intake airflow in front of the GPU (left side of the case) would be blocked by the GPU itself in the E-I7.

When there's no obstacles, an exhaust fan works well in the E-i7 because it draws air from the vents on the top, across the motherboard and then out. With the GPU in there, it blocks that airflow. You probably need some kind of air pushing onto the GPU and then exhaust elsewhere to draw the air out. I would try fans blowing in on the GPU side and fans blowing out on the opposite side but it will probably take some experimenting. That's a lot of stuff in that little case.

Hi Stardog and thanks for your suggestion,

Next week I will receive my fan guards, reverse the 2 inside fans to exhaust (the external ones in front of the GPU are already mounted to intake) and post some photos (interior, stress tests).

Hi, I have just received my fan guards and I thought I should post a small update:

- I have reversed the 2 fans inside the case to exhaust heat instead of in-taking cold air
- I have removed completely the 2 fans mounted outside the case in front of the GPU that were also in-taking air (I really had a problem with the aesthetics ...)
... and I might say WOW, what a difference in temperatures...

Just a short comparison:

- Furmark 4xMSAA, 30 min run, GPU load: close to 100%, TDP: 97-102%, Before: GPU throttling at 80oC and orange color in GPU-Z at PerfCAP due to thermal, After: 77-78oC, NO throttling, green color in GPU-Z at PerfCAP;
- 720p movie with madVR level 5 / the hardest test (Chroma: Bcb75AR, Image Up: Lanczos3AR, Image Doubling: NNEDI 32neurons, Image Down:CatmullRom AR), GPU load: 62-70%, Before: case very hot, temp close to 78oC, After: case barely warm but with a lot of heat exhausted, temp around 65oC.
- BluRay rip 1080p with the same madVR level 5 / easy one, GPU load:26%: Before, 60oC, After: 50-52oC

all the above with the LNA adaptor on the CPU fan (1800rpm instead of 2500rpm all the time) and full 1400 rpm on the exhausting fans.

As stardog and goodbyegalaxy pointed out it seems that with my previous set-up, heat was trapped inside the case and hence the high temperatures.

I should also say that there was no problem with power even with GPU at 98-102% TDP, the picoPSU 160 +192 w power brick managed the load with no problems.

Next test: Furmark 4xMSAA + Prime95 2 threads (I have learned that in order for Furmark to max out you need to leave at least 30% CPU load spare on a dual - core). If test is successful meaning no throttling on GPU and temps < 80oC and CPU temps around 65oC than I will consider that I have also a very compact and enough powerfull gaming PC!

That's great news. A lot of times it really is about messing around with the fan configurations since what is inside each build tends to be different and therefore affects the airflow.

A last update:


I have run simultaneously for 30 min:
- Furmark 2xMSAA (4 was overkill for the GTX 750 ti and hard to achieve in very demanding games)
- Prime95 2 threads max. power consumption


... and results:
- GPU: 99% load, 95-101% TDP, temp. stabilized between 78-79oC - no PerfCAP throttling due to thermal, constant 40fps in Furmark
- CPU: 76-86% load, temps between 65-68oC


The only issue I've seen were some very short perfCAP in GPU but ... due to power, nothing to be worry however since the bar remained green, I think it was due to the fact that the CPU was also reaching its max TDP or very close to it. The picoPSU 160 should sustain for very short periods even loads of 200W so I think this helped to mitigate the short spikes in power increase from throttling the GPU.


Overall I think the PC can sustain any game within reasonable temp and power margins but will be somehow borderline for very short moments ...pretty satisfied however with the results!
