looking to update case

pc specs:

super lanboy case
thermaltake silentpower 480w psu
1gb corsair xms pc3200
9700pro aiw
P4 2.8c (D1 step)
audigy 2 zs
nec 3500ag
lite-on 52x
2 seagate 160gb barracudas


now i thought that buying the lanboy case was a good idea seeing how it lite and i could transport when i needed too. actually its been more of a pain and has hindered cooling as well as ocing. now im looking for a enclosure that has a good amount of fans, a window with fan over the cpu (for mod), and mobo tray if possible. should i get a new psu as well?

Look at the Ultra cases, you can see them at tigerdirect. Maybe there is something there that will work for you? Only thing I think they are lacking is the removable motherboard tray.
