These are much different than the typical 6-8-9 slot riserless boards where the slot spcing is too close (44 mm). 

Card Spacing between this 12 GPU riserless = 65 mm. This handles almost all thick RTX cards, which other riserless typically dont

1) Listing is for mobo only. You will need LGA1151 CPU, DDR3 Desktop ram on your own. I can provide with custom invoice.

2) It needs ONLY PCIE power to run, ATX PSU not required. Can run off bitmain, HP server PSU with breakout boards etc.

3) Board is in two piece, that bridge together (Mini ITX + Extention). Mini ITX needs 2 PCIE ports, Extention needs 4-6 power ports plugged in. Dont plug in ATX, CPU Power, not needed.

4) No special frame is required hence assembly is extremely quick and easy. The GPUs stand in the slots without any other support. 

Installation instructions, pay attention to powering the mobo the right way.

 

a) Plug in CPU + RAM + CPU Fan in mini ITX section, dont connect the extension yet.

b) Recommended to connect VGA monitor for first run.

c) Plug in 2 PCI 6 pin power to 2 ports On the side of the board, closer to CPU. That's all power you need for mini-itx piece. Nothing else.

d) Power on, ensure bios screen is shown. Change "Network stack - Disable, CSM - Enabled" So you could boot through hiveOS/SMOS USB. Will recommend not using SSD and just run off USB.

e) Connect extention board. Extention board has 10 power inlets. Connect 4-6. All are not required.

d) Slot in GPU and POWER GPU DIRECTLY FROM PSU. DONT TAKE THE POWER FROM MOBO. NOT NEEDED.

Have sold huge qty and have happy miners who have made full switch. 

Ships from USA/Indiana. The pics are of actual product and assembled rigs. The auction is only for single Mobo.
