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].

While the hifive is an awesome proof of concept 3,5 k$ for essentially something performing roughly as well as a raspberry pi seems prohibitively expensive for now.
