Biostar TB250-BTC+ motherboard. Intel B250 chipset LGA1151 socket (Supports 6th & 7th Gen Intel processors) Supports multiple GPUs for mining DDR4 memory Multiple PCIe slots 6 SATA ports. The motherboard is clean and in excellent physical condition, but I do not have a compatible CPU and RAM to test it, so it is being sold AS-IS / UNTESTED.
