New to e-GPU but have built plenty of specialized computers. My question is how much of a host do you really need to host the e-GPU? I'm looking at building a small set top box size computer with a mini-ITX MB and add a ASUS ThunderboltEX II for the connection to the e-GPU enclosure. My thought is all the host has to do provide a place for the CPU, communications to the PCI-Express buss for Thunderbolt 2 and then have USB for peripherals. If I can pull this off with a AMD A6 or X4 I can build a great host for about $300-350 and put more money in the GPU. Thoughts?
