I hope that PSU isn't crap because it's what I have in my personal system. I'm running 5 hard drives including 2 Raptors, overclocked A64/3000, 9800 Pro, 2 sticks of RAM, sound card, 2x 120mm fans, CD-RW drive, floppy off of it.
This Thermaltake is the best value for the money IMO ($38), unless you think you need more than 420 watts, which most everyone doesn't. One easily gets into the $70 and up price range beyond this PSU.
