Biostar introduced the TB250-BTC D+ motherboard for crypto-mining builds. This board appears to be a re-brand of Colorful C.B250A-BTC PLUS V20. This is probably a case of Colorful piggybacking Biostar to reach markets it cannot (yet). The socket LGA1151 motherboard supports 6th and 7th generation Core "Skylake" and "Kaby Lake" processors, with basic I/O connectivity, and a single DDR4 SO-DIMM slot. The star attraction here are eight PCI-Express x16 slots with 2U spacing between them. One of these slots is electrically x16, the other are x1 (you only need x1 for mining). There are also eight 6-pin PCI-Express I/O ports, so the x16 slots are powered. The board is 195 mm wide, and 485 mm long, designed for mining cases, or something miners put together themselves.
