The Dell Precision I have experience with make very little noise on normal operation. They do ramp up when loaded, but nowhere near rack server levels. I have a 5820 [only 2x 16x electrical, but all 16x physical] and two dual CPU T5610s sitting a couple feet from me. If I have an all core load...
To continue the OT: I tried using a 43in 4k panel as a monitor. I found I could only use 1/2 of it at a time for productive work, which lead to me using 2x 24in monitors stacked which I liked a lot more.
The one in the picture has bent pins and a bent VGA. So probably do need a lot of rework.
This is not who I bought one of these boards through in Jan 2019, but IIRC there were multiple sellers about that time.
The EVGA SR-1 seemed to have started this board segment. Asus has made a similar layout of board for the last few generations of E5 V1-2 & V3-4. I cannot think this is high enough volume to need multiple sources.
It is kind of interesting to see only 1GbE.
