can't really determine the size. I'm not even really sure how to pull out the PSU - it's like it's the entire base of the case. The sound is really driving me F-ing insane - just high enough a frequency that i can hear it over pretty much everything (TV, fan, heater, airconditioner). Dell charges $90 for a refurbished version of the PSU. I'm not 100% it's the PSU, but i've tried putting a pen on all of the inductors on the board and stopping all the fans one by one - the sound still persists. Is there a way I could unplug the motherboard power and short pins on the PSU to make sure that's it?
EDIT: Just shorted the pins (ie. no mobo plugged in) - and like I've said, I've tried unplugging all the HDs, Cd-drives, and fans... so I guess that leaves the PSU as the only culprit.
It actually looks exactly like that 1U server power supply (except my PSU is 460W)... this model i believe: NPS-460BB-E
I don't understand though, because all the images I'm seeing on the ebay pages for this model, I don't see molex connectors or SATA connectors (for CD drives, harddrives): http://search.ebay.com/search/search.dl ... =NPS-460BB
