I just bought a Cooler Master centurion series case for my next project. all i can say is WOW!! its a very friendly case to work on especially with the easilly removable front. the entire front is a mesh metal with a very thin foam layer behind it. makes for a very nice air filter. the only SINGLE disadvantage is the MOBO tray is NOT REMOVABLE!. i'm okay with that tho. theres enough space to work around it. heres a link to the newegg pics.
centurion 5 CACi bought mine with the clear side window and to do that it cost $85 and it came with a MC 380w PSU. (i think thatll go in my folding rig soon.) you can get it in a few color flavors too.
the other option was another CM product, this badboy here:
Centurion 530you can get either one of these with or without the side window.
they both look like theyd wear a tux to a party.
