BIOSTAR has two ATX motherboards that are perfect for setting up a Bitcoin mining machine. One, based on the Intel H81 chipset, the Hi-Fi H81 S2 is an Intel socket 1150 board and the other, the H61B is a socket 1155 board.

In the Bitcoin world, a "mining rig" is a computer system used for mining Bitcoins. It can be built specifically for mining or it could be your everyday computer for gaming and surfing, and is used to mine only on a part-time basis.
