Lack of a back powers witch but I can deal with not having one.
Currently running an I7 950, 2X 6870's, 2 Keyboards, 1 mouse, 3 other USB devices, 3 Harddrives, 2 Optical drives, 6 fans and a water cooling kit, with headroom to expand and no substantial power fluctuations.
Great stable power!
All cables are modular!
80 Plus Silver!
4x PCI-E 6+2pin (and 2x PCI-E 6pin), means great for SLI or CrossfireX
No power switch in the back? (not a huge deal just would be nice if it had one)
Never heard of Silverstone, the Winnipeg location was out of the brands I know so I asked someone to help me. He told me a bit about it and showed me a review online. Very happy with my purchase thus far, went online and read some other reviews and they all seem positive.
