Update: All finished now. The hi-fi ended up moving up a shelf. The Wii has moved about 8 inches to the right to accommodate the VGA Switcher's new home. Between them is Wii Remote Number 2. On top of the Switcher is the Mouse Dock and Wii Remote 1 in its charging station. Behind the Switcher, angled through the gap at the side of the book case is my USB fan.
Beside the Wii on the right is currently the Eee, but that gap is eventually the Mac mini's home. To the right of that gap are the Wii games. Most of the Wii Accessories moved into the Wii Games' old home, the others have entirely new homes. For example, my 3 wheels (The Ferrari multi-format one and the two Wii Remote shells - including the official Wii Wheel) are in that redundant PS2's old home.
I swapped the power strips so the 6 is at the back powering everything, the 4 now upfront for charging things.
Final big change, I moved the monitor back and the speakers forward, so there's now way more space on the desk.
It's a pretty nice setup. I'll have some pictures soon...
