Built this as a budget gaming pc for my son. Everything works great together and went together easily. we have had no heat problems with heat-sink and fans that came with the processor and case. He's using it for Steam games on Linux currently. (He's saving for Windows :o) We had to do a bit of work to get the drivers loaded for the motherboard and graphics card in Ubuntu. I'm sure that will all go smoother when we load Windows. So far it plays L4D2, Dota, Team Fortress 2 at max graphics settings and it performs very well. Once we get Windows we'll play more graphics intensive games and I can update my review.
