I recently bought an Antec SX-630 ATX case from Provantage with a 300-watt 
PS -- seems like I paid about $70 plus shipping for the whole thing.  Very 
sturdy, two fans, easy access, yet little fan noise, and the PS appears to 
be totally silent for RFI.

That being said, many inexpensive power supplies these days leave out 
essential AC line filter capabilities.  you can put this right by swapping 
the power input jack for one of the Qualtek units with an integral AC line 
filter -- I think they took these over from Corcom, whose filters John W0UN 
recommended a few years ago.
