really tempted to go SFF, and an X79 offering is pretty amazing, but there are too many things I don't really care for with this design
1. 500W bronze should be enough, but when Silverstone is including 600W units in their higher end Sugo series ITX cases, it kinda sucks that Shuttle cut that corner. There really wouldn't be enough breathing room for a dual GPU card, or even a large GPU like with the 580 (and possibly GK110) as well as having any chance of overclocking the CPU...which brings me to:
2. the cooling solution is pretty clever, but how effective is it? I can't help but doubt its effectiveness on a sixcore SB-E chip. I imagine its good enough, but certainly not for any hefty overclocking. It would be really nice if they instead looked into some sort of custom closed loop water cooling
3. I'm tired of these SFF designs being neutered with the task of finding room for a ROM drive, that space could be used for a radiator for a water cooler I discussed in the previous point ROM drives are becoming less and less important and thus their negative impact on a SFF is more and more unappreciated, especially when external USB drives can more than do the job. Why can't these guys design a case without the space for a ROM drive and instead design a matching external for all those chumps who absolutely have to have one?
other than that I do love seeing products like this, but if I had to go SFF this round I'd be more inclined to go with something like Silverstones SG08 + ASUS's P8Z77-I Deluxe (which they managed to cram 10-phase power into thanks to a clever riser card) and a heavily overclocked Ivy Bridge chip, as I would be surprised if the CPU can be overclocked much higher than stock/turbo levels on the SX79R5
the GTX680 sounds like it would be a perfect match for a SFF gaming system regardless
