Pretty nuts.
There's a lot of fans in there for a water cooled CPU/GPU.
I'm still not sure about PCI-E SSDs, as they are internally just RAID 0 arrays, which means you lose TRIM support; I think that a single good drive, like a Vertex 2, (probably the original rather than the 'E' series, just for longevity), is more than ample, then you just buy three+ 1.5TB drives and run them in RAID 5/0 depending on how much you value your data.
