I have a case from a dvr that I thought it might be a unique computer case. its approx. the size of a vcr. I hoping to put some extra components I have lying around into it and give it the appearance that its simply a dvr, but add wireless keyboard and mouse, so I could, if needed use it as a computer, but mainly stream our online services, and youtube.. now the issue.. Power supply I have, I am not sure if it will fit. also I only lack cpu and heat sink. (and potentially another video card). I was wondering about suggestions for low profile heat sink and possibly video card.. and maybe power supply if I can't make it fit. its a motherboard from a dell xps 8300 thanks for any ideas. also can I just somehow use the power button from the dvr,
