Quite a few motherboard manufacturers are designing boards for crypto-currency mining rigs. The idea behind these boards is to serve up as many PCI-Express add-on card slots as possible, so miners can wire those slots out through risers, and drive way more than 7 GPU/ASIC cards. This makes for a better investment than building additional machines for more than 7 cards. Crypto-currency mining isn't bandwidth-heavy, and so even PCI-Express x1 provides sufficient connectivity for mining cards. The H81A-BTC V20 from Colorful is a socket LGA1150 motherboard, which takes in old "Haswell" and "Broadwell" CPUs, a pair of DDR3 memory modules, and puts out seven PCI-Express slots, of which one is x16, and the rest x1. The board draws power from 6-pin PCIe and 4-pin Molex, besides 8-pin EPS and 24-pin ATX, to cope with add-on cards that don't have their own power sources.
