Whoa, downvoted to minus 4. No idea why. In my 9 years of HN, this is my worst downvoted comment. Maybe people thought I was being off-topic? Let me clarify a bit for the public here why the comment is relevant: in the crypto mining community, some groups are looking into what minimal single board computer can provide a PCIe signal to connect a single GPU. Idea is to be cheap and reliable. If you have a many-PCIe board failure (http://bitcoin.zorinaq.com/many_pcie/ http://bitcoin.zorinaq.com/many_pcie/) you have 10-20 GPUs going down at once. Not good. By isolating each GPU on its own motherboard, you can isolate failures, thus increase mining profits. When I saw the OP mention cryptocurrency in the blog post, I thought hey maybe that's what he is looking to do...
