I always recommend the Rosewill R5600 series (be aware that the 5601 has a dedicated floppy drive bay - IOW only a floppy drive will go there, the 04 and 05 have a generic bay in which you can put any 3.5" external device) and the R6A series. Right now they are at the best prices I've seen them for a while with many models at $40. +sh. AFAIC, these are the best cases at the low buck. You'll be glad you spent the extra on down the road. If you expect to use long add-on cards, the 5600 series is a bit better for that with 11" of card space.
And this:
i-Star 500W (they used to have a 400W that I'd recommend, but I don't see it any more - try Froogle) would be a good PSU to go with (unless you can stretch your budged to cover the Enermax I'm selling

). Remember, the PSU is the cornerstone of a stable system. And just like the case, you will be glad you spent the extra on down the road.
Of course, check the For Sale/Trade section and eBay as you might come up with an excellent PSU that you otherwise couldn't afford. 380 to 450W unit with the power proportioned to the rails properly would be plenty for the system you mentioned.
