BIOSTAR has created a crypto currency (such as Bitcoin) mining motherboard, the BTC-24GH, with 64 ASICs on-board that offers 24GH/s performance which is equivalent to more than 30 ATI 7970 graphic cards.
In the Bitcoin world, a "mining rig" is a computer system used for mining bitcoins or other crypto currencies. 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.
With the rising price of Bitcoins, GPU mining can theoretically be profitable. What is needed is a system that can do enormous amounts of mathematical calculations. Up until now, the best way to do this is the GPUs in graphics cards. Now there are ASICs (Application-Specific Integrated Circuit). ASICs are good at one thing only, solving mathematical hash functions. In this case, their strong hashing power and low power usage, making it very efficient to use.
The cost and availability of the BTC-24GH has not been released.
