Racked at the house...
Dell C6100, 4x { 2x L5639, 32GB ram }
Dell C1100, 2x L5639, 48GB ram
Dell Powerconnect 5324 with a permanent fan error because I unplugged it, the noisy bastard.
Ubiquiti ERL-3
Maybe half full of SATAs, most of which are spun down. Further sliced into VMs because I like to play around with KVM/ESXi. Mostly used for ADC, media serving, local backup, test build environments, autodeployment script tests, etc. It'll draw 6-8A @110V easy with everything spinning max load, but it usually idles around 1.2-2A as I only wake 3 of the C6100 sleds on-demand. Config exactly mirrors my colo, which pays for both, but is not my job.
Workstation's notable components are the G530, GTX460, a cheap-as-it-comes asus MB, and 3x displays.
Half a dozen or so ARM SBCs (rpi, udoo, beaglexM, etc) doing menial things like RTP audio endpoints, ethernet-attached GPIO, openelec.
