Colorful Intros H81A-BTC V20 Motherboard for Cryptocurrency Mining
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.

Cheapest one I can find is 110$, and the other Board vendors are >125-250$ currently.
Who is that intelligent to buy a board that should be around 50-60$?
For average 80-200$ you get a used Workstation for min. 4 GPU's
including:
- 750W-1000W Power supply,
- HDD,
- CPU
- Memory.
If you choose carefully the CPU is still good enough to mine some xmr.
If you are lucky there is a Quadro card inside that still get you some bucks.
If you are really lucky you get a workstation with 4G Decoding Option in Bios and 5-6 PCI express Slots.

Either way I wonder how long this cycle will last. I still have a cheap board with a bunch of slots I used for mining back in the day. But I am short on cards to really make it worthwhile anymore.
Also, buying an used graphics card is a hell of a risk, I bought two used HD5870s when the last mining crazes were almost over, and the cards were pretty "raped" by mining.
