I'm using a P180 non-windowed case. It's a decent case.
Warning: I hope this case won't be for a LAN PC. It weights a TON when fully built. Also, just a word of advice. First thing you do, is remove all the stock case fans, throw them right in the garbage. Buy better case fans. The fans that this case comes with are the worse fans i've ever seen. They barely move any air. Secondly, make sure you spend some time on wire management. The separate compartments make the motherboard area very cramped. If you don't manage your wires right, you'll defeat the whole purpose of having two separate compartments.
