Those looking to generate some extra cash by mining for Bitcoin now have a couple of new hardware options courtesy of ASRock. The motherboard maker has released two new motherboards designed specifically for mining the digital crypto-currency that's topped tech headlines this year.

Both the H61 Pro BTC and the H81 Pro BTC come with a 100 percent all solid capacitor design. Additionally, the pair support dual channel DDR3 1600 memory, dual VGA output options of D-Sub and HDMI, Realtek Gigabit LAN and 5.1 channel HD audio.

The cheaper H61 Pro BTC only supports second and third generation Intel Core series processors while the more expensive H81 works exclusively with fourth generation Haswell chips from Intel. Both boards have six PCIe slots for up to six video cards although the less expensive model is limited to one PCIe 3.0 x16 port and five PCIe 2.0 x1 ports while the H81 features one PCIe 2.0 x16 and five PCIe 2.0 x1 (go figure).

The H81 also has better connectivity options with two SATA 3, two SATA 2, two USB 3.0 and six USB 2.0 ports. Conversely, the H61 only has four SATA 2 and 10 USB 2.0 ports although it does have some other interesting features like a built-in dehumidifier designed to keep your PC free of moisture at all times.

Unfortunately since these boards were just announced today, I was unable to find them for sale just yet nor do I have any idea how much they will retail for.
