Thanks Jeff, however for the time being I'm going toonly run a few feet of
Cat5 cable. The biggest problem I have at home and work is way to many
things to plub in around my PC's Right now at work I have all of these on
there own plug right next to my desk.
1) Notebook
2) Two LCD screens
3) PDA
4) Cell phone dock
5) Radio
6) Bluetooth headset
7) Finger print reader
8) 2 Routers
9) USB Hub
10) external DVD Burner
11) Computer
12) Speakers
13) Heated Chair
Probably something I'm missing, but I'm sure if everyone would use a common
power voltage you could make a single plug that would power 4 or 5 low
voltage items.
