Compact gaming desktop

[mr_ant]

Hiya guys, i was looking for a gaming case but want it compact, i was going to get the CoolerMaster Elite 120 but heard it has loads of problems with the cooling inside it, so i was looking at the bitfenix prodigy case, i also wanted to ask is it easy to build it because i havent done it before, do instructions come with it? was looking through the PSU's and not sure which ones would fit the case, i was looking to put inside it the Amd A10 5800K with an Nvidia GTX 660 graphics card, not too sure about the different types of motherboards and not too sure what the differences are, i am looking to pay Train Simulator 3 and also Call of Duty and Battlefield 3, thanks for any advice you have
