Look, I do have some knowledge.
I have a gaming PC that I built myself two months ago. I was merely looking for recommendations on a HTPC since Ive never built one before. What works well for this purpose, has a small form factor, and still allows a bit of gaming? I only want the gaming capability because I want to have my mates over to game some times. However, its not important that it has a cutting edge graphics card. An ATI 5770 or 5830 suffices most likely. I also needed a bit of help getting it within budget constraints, something like 400 gbp.
I prefer the Athlon II X4 630 because its cheap and has quad cores. Also Toms Hardware recommends it for budget video encoding, which I may do.
