I have built to may computers lately for other people and have made the decision that I need to build a sweet system for myself. I have the age old question (and it's getting older)... that is, old server gear or new consumer? I would be going with dual xenon X5690s (6 cores @ 3.46GHz base each) and supermicro MoBo with 7 x16 pcie 2.0 slots and 12 ddr3 dimslots (witch I would fill with 8gb sticks… of course). On the other hand your average 8th gen i7. Buy the time I purchase all the pcie adapters to gain modern i/o it will be around the same price. Regardless I plan on water cooling it with an extremely clean, custom case. Thanks for your input.
