The case is fine, only just bought it too.
It's not huge but people have already fit h80i's in it.
The problem I'm having is because on the mATX boards, the CPU is very close to the left side, so when both fans and the rad are on the rear, they basically cover the CPU.
If I was to buy a new atx mobo, like the one above, would this or would this not fix my problem?
