So I'm sleeving my power cords in my big machine. Not really a mod, per se, just trying to do some tidying up inside the box. Note to all - make sure you have the molex connectors wired up properly when you put everything back together. I wasn't paying attention and wired it up backwards ( I think, still have to investigate. Flicked on the power to the box, and watched the dreaded blue smoke come pouring out of the drive bay. Needless to say, I've got a pair of 160 GB hard drives that are useless now until I can find replacement circiut boards. I think the drives themselves are fine, just have to replace the boards. Seagate is going to send a replacement for one drive, but the other is OEM and not supported. Not a happy day for me yesterday. 320 gigs down the toilet, hopefully only for the time being.
