When The Tech Report were asked to review the new Dell R810 2U server they jumped at the chance.  Inside lies dual octocore Xeon X7560s, 128GB of DDR3  (of a maximum 500GB), four SAS 6Gbps drives (which they swapped for Vertex EX SSDs) and a pair of 1100W PSUs.  It is impressive to see all that shoved into a 2U rack but Dell went further with internal SD card readers for easy HyperVisor use, external LCDs to display realtime hardware and software data and a casing much more attractive that you usually see in a server room.  The performance compared to a dual X5670 system varied so you should probably read the review before you go spending $23,000 on the server.

"Intel’s eight-core Nehalem-EX processor and Dell’s R810 chassis combine to form a new class of 2P server, with huge memory capacity at a lower price point."
