Before you move

1. Back up any data that is stored only on this computer
2. Take a photo of the rear of your computer. This will help you know where to plug the cables back in at your new desk.  You might even prefer to make small labels or use color-coded stickers for the cables.
3. Disconnect all cables.
   1. Neatly coil loose cables up and place them in a box.
   2. Coil any remaining cables around their accessories (mouse/keyboard/etc), and place those accessories in the box.
4. Place any computer(s) or monitor(s) back in the original boxes if you still have them, otherwise transport with care.
