With that amount of RAM needed it sounds like it's designed to be low and mid-end PC resistant too.

the first coin exclusively designed to run on amazon EC2. Nice.
The amount of Ram needed is kinda an easy fix. Just point your vram at an internal flashcard of 32GB and you are all set...maybe some messing with RAM Hog, but that shouldn't be a show stopper. It may be a bit slower than actual RAM, but it won't be that much slower especially if it is internal and probably low latency with USB3.
Just google: using flash as ram...and you will get a ton of advice from like 6 years ago even...
