really nice and clean setup. I really like the Noctua fans. They are on the pricey side of things but very nice non the less!
Although I would say with you running ESXI if you could put more ram.(max out the mobo) if you can.
I notice on my server I am ESXI server that the VMs take more ram then Cpu power.
