In case people have a hard time finding prices for this, my vendor gives ~57k GBP ($85k) as the lower end price for configurations with that SuperMicro cabinet, 64 cores (8x 8-core CPU's) and 2TB of RAM. Dropping to 1TB lets you pick from a lot of cheaper cabinets and so the price drops by quite a bit more than half for the basic configurations.
2TB can be one server: http://www.supermicro.co.uk/products/system/5U/5086/SYS-5086...
An expensive server for sure... but it's just one server.
