After a fairly serious think on this one. Smallest possible build/setup with full sized GPU and a 2nd 4x PCIe.
It only needs to hold 1 SSD.
It does need to be able to take a decent sized card and be able to cool it.
Planning to infiniband (10Gb+ network) my house, have storage in a central box and a port in most rooms so want a tiny box I can take wherever in the house
Been looking around and can do most of the setup on the cheap for about 1k.
