Re: question.. not sure where to post..!!

While you wouldn't necessairly be able to use the same power supply or 
ethernet connection, this would not be that hard.  I am continuing my 
education by taking electronics class here at the school.  One of the 
classes is computer interfacing.  In this class we use a Parallax Basic 
Stamp 2 to control various devices.  This could be adapted to control 
two power switches using one button while keeping the switches completly 
isolated from each other.  The other thing that could be done is to 
place a small ethernet switch or router inside (or outside) the box.  
Connect both to the switch and then there is only a single connection to 
make.  Lastly, place a two system KVM switch inside (or outside) the box 
for system installs or troubleshooting.  This would give you, at a 
minimum, the following connections:

1 Keyboard
1 Mouse
1 Video
1 Network
2 Power (1 for each power supply)
Other misc. connections (USB, Firewire, S/Video, Audio, etc)

As for CD/DVD drives and floppies, depending on the OS and hardware you 
could use USB versions when you need to use them.

Hope this helps.
