Well, its been over a week and my search has been far from fruitful. I think I'm just going to go with the case linked to below. It's affordable, not half bad looking, and has a reset button(ill explain in a minute)
After sorting through all my computer components over the last week I came to realize I have allot of components that would be great for such a project, instead of buying all new hardware. I have an HD4870 that's currently just sitting on my book shelf, and a Phenom X3 that is doing nothing right now. So I figure Ill get an AM2/AM2+/AM3 mobo, start with the Phenom X3 and eventually upgrade to a Phenom II X4, the 955 BE is dirt cheap on new egg now. A Phenom II X4 and an HD4870 will be more than enough power for a steam box/htpc. Infact that exact setup is what my girlfirend was running before I gave her my HD7870, and that setup took everything we could possibly throw at it, even BF3 at ultra settings, although high settings gave a smoother frame rate.
As far as why its important that the case have a reset button. I currently use a Xbox360 controller that I modified the cord on to make it longer, I'm sick of having that LONG cord going across my living room floor, and the controller has been through hell and back and is starting to develop a small short in the cable (I've had this controller since the 360 was first released.) So what I'm going to do is purchase a wireless 360 controller receiver, and connect it internally to one of the unused USB headers on the motherboard, I will then mount the receiver on the inside of the case and solder a small pin header in place of the pairing button on the receiver, I can then connect the reset button on the case to the receiver and use the reset button on the case to pair my wireless 360 controllers.
who needs a reset button on a PC these days anyway!
Further more, one last reason I chose this case. This case has an optional LCD module that can be installed, I'm not the slightest bit interested in having an LCD screen on the front my my case, I cant read it from my couch anyway. However, I am interested in the fact that there will be a tinted portion of plastic on the front of the case that you cannot see through, but infrared would have no problem passing through...catch my drift. I can remove the IR receiver from the board on my MCE remote receiver and mount the board inside the case and then just using some short lengths of lead wire I can then place the IR receiver just inside that window.
So in the long run, this case will allow me allot of flexibility as far as hardware upgrades are concerned, it will save me money now, because I can use parts I already have to start with. Not to mention it will allow me to make both the 360 receiver and the IR receiver internal, after all is said and done I'll have two USB ports left on the hub I plan on butting inside so I may as well add Bluetooth while I'm at it.
