Apparently some Bitcoin miners haven't moved on to ASIC-based mining rigs. For these, BIOSTAR unveiled the TB250-BTC, a motherboard with a number of PCI-Express slots, so you can cram in as many GPUs/ASIC cards as possible. Since mining isn't a bandwidth-heavy application, a number of PCI-Express 3.0 x1 slots besides an x16 slot wired to the CPU, should live up to the task. The TB250-BTC is built in the ATX form-factor, and is based on the Intel B250 Express chipset, with support for Core "Kaby Lake" processors out of the box.

The board draws power from a combination of 24-pin ATX, 8-pin EPS, a SATA-power, and two optional 4-pin Molex power connectors, to stabilize power delivery to the add-on cards. It uses a simple 7-phase VRM to condition power for the CPU, which is wired to two DDR4 DIMM slots, and one PCI-Express 3.0 x16 slot. Storage connectivity includes six SATA 6 Gb/s ports and one 32 Gb/s M.2 slot. 6-channel HD audio and gigabit Ethernet driven by a Realtek RTL8111H controller, make for the rest of it.
