These are a great deal @ $38.
The Truepower line is NOT a higher-grade line... Antec split their line to make the budget SL series for their cases to save some $, then cashed in by selling 'em retail too. Truepower is similar quality to this but all dressed up. Granted, things are changing, PSU now have more bias towards 12V rail support which is more of a problem on a 250-350W PSU than on one 400W or higher.
I agree the fans weren't optimal though, I suggest swapping in a Panaflo FBA08A12M for those that have speed control, but I suspect those that aren't labeled do still have speed control.
