Ive started to get the paint on the walls, going for grey and a blue colour combo. Lowes had a deal on Valspar reserve and Olympic one which goes on very well

Otherwise the collecting dust starts causing the internal components to be unable to release their heat effectively, leading to the device failing. That and pulling them out to get them open for cleaning means moving wires and risking damaging those in the process.

Better to have a door on the rack with a filter panel of some sort. This way the ambient air gets pulled through the filter first. You'd be (unpleasantly) surprised to see how much gunk collects. Especially if there's pets, smoking or the area gets a lot of foot traffic. But you'd also need to consider if that introduces undue restrictions on the HVAC system, which can greatly impact it's performance/lifespan.

I make this point because the way you've described it makes it seem like a lot of the room's return air depends on going through that route. I don't know that I'd make that choice because of the dust and it's impact on the gear (both AV and HVAC).

I appreciate your advice but I took all this into consideration over the couple of years planning this out. OCD can do that to ya and dust is no friend of the obsessive.

The room has a single point of entry which is closed off to the rest of the world. The only way air circulates through the room is by the pair of supplies in the rear. There is a pair of pantyhose stretched across each boot behind each grill on EACH end of the supply legs. This prevent dust from entering the room and are easily vacuumed when the need arises.

There are two returns. One opened to the whole room in the front and one inside the equipment room. They both draw air across the whole room. The Panasonic exhaust fan is rated at 440CFM via it's 8" inlet. This is split into a pair of 6" lines in the HT room. So far it works pretty good. The HVAC is a self contained unit (minisplit) located in the room. It has no interaction with outside air and actually acts as a psuedo air filter itself due to the filters contained within it.

"This aint my first rodeo "

FWIW, my profession also dictated a lot of my design. I'm an EE and work in the technical support arm of Alcatel-Lucent supporting engineers & technicians at Verizon, Sprint, AT&T....I've seen plenty of of routers, cell sites, switches...meet their demise and host all sorts of issues due to dust, hair, insects...infiltrating the equipment.

Great thread!


I came across a ERK-4425 44RU locally. Would this be suitable for normal audio equipment?

Well, I'm glad to finally get to throw my hat into the ring! Its still a work in progress, but here is my rack that I pulled out of an abandoned building and shined up! Equipment from bottom to top: Denon X3000 receiver, HTPC in Silverstone LC17B case, Oppo BDP-103D Blu-Ray player/video processor, Xbox 360, and a PS3. Everything is being powered by a Tripp-Lite 2440Watt on-line UPS. I also used Middle Atlantic Custom shelves/Brushed aluminum face plates for everything.

I have a lot planned for the rack, but I quickly ran out of money hahahaha! I still need to run the networking for everything as well as all of my serial cables for the automation, but I'm getting there. In the future I plan to add a Parrasound A31 amplifier for just my front channel speakers and let the receiver take care of the surrounds. I am also hoping to get some crowson actuators and a proper amp for those as well.

What are most of the faceplates made out of on common racks? I have a CNC Plasma table and I was considering cutting them out of stainless or aluminum? Any preferences on material?

Which ever is cheaper is what I would get. Doesn't really matter because I am assuming that you are going to paint them anyway. The face plates that come from MA are made out of some type of steel. Can't really tell what type because they are painted, but I doubt it is stainless.

I expect any anodized face plates are aluminum. They are very light weight.
My blank face plates are all steel save for one aluminum . My ventilated
plates are all steel.

My ventilated plates were ordered, while the ventilated and blanks (and most
of my newer style shelves) were all ebay'ed on the cheap. Hence the mixture.
They'll all be getting a matching rattle can hammered finish in the spring, once
I am done with some electronic upgrades.


I've been toying with investing in a CNC router and make my own MDF face
plates, as I tend to upgrade often. So I think your idea has some great merit.
You could even invest in a metal brake, and make your own shelves, with that
plasma cutter.

I spy a LG FP14K (clone?) and a seriously awesome custom painted iNuke...

Niiiice!!!

All of my face plates are anodized aluminum and the vented blanks are steel.

That'll work. I have tons of scrap 14ga that I can use for the face plates. I think a CNC router would be fun to have. I do have a metal brake and hadn't even considered making my own shelves. I think I may now. I hate to buy anything that I can build myself.

You also might check out Craigslist's for used racks. Buying one with shelves
might be another good option as you could modify the shelves for ventilation and
clamp down slots.

The bigger savings is in face plates and shelves tend to be reusable when making
electronic upgrades.

Yes, the clone powers the 8 FiCar IB318'. 4 up front and 2 each in each rear corner. The rear corners are on a 45degree angle.

8 18" IB subs in Concrete Bunker HT

The iNuke look so distracting being silver in the black rack. I really didn't do anything special with it. I just took some grog tape and taped the glossy part in the front. Then I sprayed it flat black with some Krylon. Best part is, I only sprayed what you see once installed. The rest of the case is still silver. The iNuke just powers the second pair of Side Surrounds since I can add delay (to avoid any comb filtering) via the iNuke.
