Hey WT - I snagged a TTGI/SuperFlower "520W" from Directron.com for my Chieftec. One of the major reasons for grabbing that one, is that it ships with 10 molexes stock. No SATA leads, and the +12V line is a little low (advertised as 18A, mine arrived and the label said 20A), but I bought it primarily to run a mid-range AMD or P4 rig as a fileserver, and to fill it with drives. I don't have any additional drives yet, but I think that it should work out. I did have some issues mounting the TTGI supply due to the non-standard PSU mounting plate in the back on the TigerDirect Chieftec, and the TTGI's fan grilles sticking out slightly though.
Btw, do you find that the opticals have any "play" in them? I'm worried that they aren't as solidly attached due to the rail mechanism used, and that it might affect burning discs due to the drive itself being allowed to vibrate slightly.
I've always kind of hated rails myself, but I couldn't pass up a decent full-tower ATX case with so many internal HD bays for only $30. 😛
