how concern are you about stability of your system?? especially you have many optical drives, demanding graphic card, and power hungry cpu??
one user review reports that the 12V rail shows 12.5V reading, 5V rail shows 4.91, and 3V reads around 3.36. 12.5 to 12.6V kinda scare me, and 4.91 might cause instability especially if you have more than 2 HDDs and a 2 optical drives
I seldom buy anything with two separate rebates, the odds are just too high against getting both of them.
Sold out now anyway.
