Here is my desk.. I wish it was always this clean.
Nothing too special but I call it home. The 3 machines on the floor (1 linux, 1 FreeNAS, and 1 windows) are hooked up to the analog ports on the secondary monitor via a 4 port KVM. That way I can use them in tandem with my main machine. With Synergy I use 1 keyboard and mouse with out having to switch all the time.
