I don't know what "prohibitvely expensive" is in your case, but there's a possibility today: Grab one HiFive Unleashed for $999 [1]: - 4 cores up to 1.5Ghz - 8Gb DDR4 ECC Ram - 1Gbps ethernet Then grab one HiFive Unleashed Expansion Board for $1,999 [2]: - SSD M.2 Connector - SATA3 Connector - x16 PCIE Connector (4 lanes of pcie2) - A bunch of other cool stuff you wouldn't probably use (SPI, FPGA, etc.) Finally grab some M.2 Drive and a graphics card ($500 maybe?). This would set you back a grand total of $3500, which is definitely way more expensive than the current mainstream but may fit within "non-prohibitively expensive" for some. The whole platform should be open source [3].
