Hi guys. I'm building noiseless PC with Intel Atom CPU and 120GB SSD for 24/7 working with torrents. As I don't need a lot of horsepower, I decided to buy this: ASRock AD2550B-ITX - http://www.asrock.com/mb/Intel/AD2550B-ITX/ This mobo, as I understand, is with Intel Atom D2550 CPU and PowerVR SGX545 GPU. It costs me about 55 euros, so price is very low. But I have few questions: 1. What low-budget Mini ITX case I should use? I think Cooler Master Elite 120 Advance is a good choice. 2. Atom D2550, PowerVR SGX545 and 4GB RAM - Enough for Windows 7? 3. This PC will be virtually noiseless, except of PSU fan?
