Last Friday my research group picked up a Compaq Alphaserver ES40 off of the MIT reuse email list. The physics department was giving away 12 of them (3 racks of 4), and we got one of the racks! The thing weights ~500lbs, but has 16 64-bit processors, each with 8mb of L2 cache! We are working on getting it up and running and are planning to do some benchmarks.
