Box works fine. As advertised. Been running 24x7 with a bunch of VMs on it for a little over 2 months. Noise levels, temps and cost to run are all within expected ranges.I've purchased from this seller before, just not on Amazon before this order. I can't speak to their support through Amazon, but I believe I've now purchased 5 workstations from them in the past several years.  Box is solid, seller is solid.
