VPS: macroexpand.com is a RootBSD-hosted VPS, running FreeBSD 10.0-REL x64 on their "Iota" plan (512MB RAM, 20GB disk space, and 250GB/mo. bandwidth). This server has been around since about 2000 in various incarnations, most recently as cellblock.homeunix.com (now defunct), and is also accessible as muze.x.rootbsd.net.
FreeBSD workstation: The main development workstation and general usage machine (where this site was until recently hosted) runs FreeBSD 10.0-REL x64. Normally, it'd still be hosted there, but our current ISP blocks outbound ports 80 and 443.
This uses the xmonad WM to primarily manage urxvt terminals which run zsh shells and an emacs -nw session under GNU screen. In Nov 2009, this machine was rebuilt to use no moving parts and minimal power consumption. Our primary exocortex currently consists of:

Windows workstation: This Windows machine was rebuilt in 2013 for games and hosting VMs. It runs Windows 7 Home Edition. It's nothing special, but usable:
This shares peripherals via KVM switch with the FreeBSD workstation. Unlike it, however, it was built with some minor beef:
