I have considered swapping our the caps and such on one of the bad supplies I have, but just have not gotten around to it (have to order the caps).
Marginal? That's being nice. For the drives that came in them, yeah I suppose, but for the 250 GB drives that are going into them now days, marginal is being very nice. As I said in one of my other posts, every time you power the unit on, you are running the risk of killing the PS because the drive spin up in most of the larger newer drives far exceeds the rated spec of the stock power supply. I suspect if the 4000 units stick around very long and more people start putting these newer larger drives in them, we are going to see more and more blown power supplies. Maybe I should put a few of these mod power supplies together just in case, lol.
Why thank you Jontz, nicest thing you ever said to me...
