I was asked to put together a quote for a buddy of mine who wanted to replace his main gaming rig with something more reliable and fast, with enough headroom to run VMware Workstation and a number of virtual machines, output the display to 5 monitors, and of course gaming. Since building this machine he started a Twitch.TV channel here and has not had a problem with it at all. He says it is so quiet he forgets that it's running half the time!
I never had a chance to run a full set of benchmarks on it, but maybe I can get him to send me the details between his gaming and work sessions. The parts I chose were based on a combination of features, budget (this and a custom FreeNAS box with 16TB of HDDs for $2300) and an emphasis on silence, quality parts, and dust-free operation. I'm very happy with the way it turned out and the phone photos don't do it justice at all in my opinion.
