Yep! E5-2680v2. Purchased from an Ebay seller.

I bought a Z600 (dual 6-core) just over a year ago, and am quite impressed with the workstation design. I expect this machine to be nearly as silent.

Reserving Lucas 5355A.

L2995B, a GNFS-189, built a 23M matrix of density 138 and should be done in about ten days. The matrix fits in 14GB, so solvers with 16GB machines can likely solve any GNFS matrix 187 digits or smaller.
