Looks like ArchLinux (the "Kernel:" line gives it away) with tint2 (bottom), conky (right) and... I'm not sure what that is in the top left corner (Cairo-Dock? I'm curious now) using something like openbox or fluxbox for a window manager.

Yeah, you got it exactly right. I'm using Openbox as my window manager, and that's Avant Window Navigator in the top left.
I tried Cairo Dock for a while, and AWN still gets the job done on less resources, but you lose a lot of customization.
