Granted it isn't an 'all Mac setup,' it encompasses a Mac and it is only one picture.
Setup isn't usually that crowded, that was just everything up there at once for the photo. But basically it is this:
-19" Dell LCD connected the the MacBook Air (1.6GHz Rev B with 64GB RunCore SSD), also the SuperDrive is up there.
-Wireless Keyboard and Magic Mouse for the Mac.
-iPhone 3G S (16GB) with the Apple iPhone 3G Dock.
-Compaq Mini NetBook with Microsoft Mobile Mouse 6000.
-Logitech Xbox 360 Remote (Controls my PC, both Xboxes, and the TV functionality itself).
-32" Dynex LCD TV/Monitor with the PC (Stats in my signature), with Razer Lycosa Keyboard and Razer Mamba Mouse.
-Dr. Dre Studio Beats on the PC monitor.
-2 Xbox 360s, the one that is visually modded is my hacked one that I play burned games on. (Subwoofer is beside them).
-The blue light on top of the PC tower is a Nintendo DS Lite with an R4 card for playing all my games (got about 2000 titles saved to my PC).
