If you don't know about the X99 platform, it is the last Intel chipset that allows both consumer and pro processors. You can go crazy on the core count (at least 22) and PCIe lanes (max 40) and quad lane DDR4.

The motherboard has a lot of features listed below from ASRock's site. The processor is an unlocked 6 core beast (3.3GHz w/ 3.6Ghz turbo) with 28 PCIe lanes. The four sticks of RAM are DDR4 2400 CL 15 4GB.

Tested with Ubuntu boot USB stick, M.2 shows up, sound out, USB, and first PCIe slot. Other things can be tested on request. Only things shown in the first picture are included.
