Seriously impressive design all around. However, I still can't pull myself to spend 10k on one when I can instead do a decked out iMac and then offload processing to ~4 custom built servers with far more total procs/ram/ssd. The only hard to replicate piece is the six channel PCI-E SSD (cost-wise).
This is what I have done for years now, and however much I might like to just for the design... I imagine sticking with it.
