I'm looking for a decent deal on 4x L5639 CPUs. I got a crazy good deal on a couple R710's and I'm hoping these will tame the beast when it comes to power consumption. These aren't quite as power-efficient as my R720 but they're a dang good buy at $310/ea with 48gb, H700, dual PSUs, drive caddies, rails, and a 60 day warranty! Going to finally get a chance to get around to my VMware testing... Woot woot!
