CCL: Need advice on buying a large memory pc

 You can purchase this kind of system from PenguinComputing and it will
 come configured with Linux.
 I can't say for 256Gb but we have purchased 192Gb RAM systems from them
 before. Modern Linux works fine there, no special configuration
 required.

 I personally would avoid anything from Dell. Cheap stuff is cheap there
 but anything more sophisticated is rather overpriced.
 If you need something cheaper you can get a 64Gb Sandy Bridge E system
 > from cyberpower. You'd have to install Linux yourself though in that
 case. I got a very nice 64Gb RAM workstation for under $2,500 there.
