This place always has cheap cases (cheap, fast shipping too). I've used them lots. I've used this case and feel it's just too cheap. The power supply holes stripped out very easy (2 of the 4), and it needs to be removed to install the mobo.
EDIT my comments apply to
this case.
A good case just seems to make a pc. Especially one you piece together outta cheaper, used parts. This
case they sell is much nicer I think.
Also keep an eye out at Fry's and Best Buy for the Antec KS-282. Great case for $50......tax, but no shipping.
