**nVidia video cards will only work without video output from the MB.
Mining RIG output can be seen only via SSH or from simplemining/hiveOS app.
I got this board primarily due to the form factor and low TDP value (~15W or lower)
Additionally, there is no need for pcie 1x to USB adapters.
It eliminates the need for ATX psus if all your GPUs are powered through server PSU.
Could provide better airflow and cable management especially if you've put the GPUs on a wire-shelf.
Costs the same as traditional motherboard, ram, cpu combo these days.
My testing was done on MMPOS (flashed on to a USB drive) which booted just fine out of box.
I did my Nvidia cards with display output both from video card and onboard HDMI slot. Neither method worked.
So the trick is to setup whatever BIOS parameters you'd need to utilize prior to installing any Nvidia cards
In my case there was nothing that I had to change in BIOS. I just plugged 7 AMD gpus. Verified display out from onboard HDMI port.
Turned off the system. Plugged in the Nvidia card and MMPOS just booted up fine. I SSH'd into the machine and was able to mine/configure just fine.
Conclusion
In these times when the prices of PC components are exorbitant, this board is definitely worth it. The only con I see is
the warranty of 30 days in comparison to mainstream desktop parts.
