To isolate noise and heat from the computer, I want to place the
processor box in the basement and have the monitor and keyboard on the
floor above. I need to penetrate the basement wall (which also happens
to an exterior wall), run straight up about 6 ft, and then penetrate
the wall again to get into the room on the upper floor. The run should
be no more than 10 ft, so I am not worried about the cable length or
signal integrity. However, I am not sure if the cavity behind the wall
extends all the way between the basement level and the upper floor, or
if it is closed off at floor level. I don't want to open up the
drywall and find out that I can't route the cables after all. The DVI
cable would need at least a one inch hole to get through, so drilling
something that big through structural lumber would be out of the
question.
Any thoughts?

As other have have said, cable length might be an issue, especially
for the monitor. My computer lives in Grandma's antique desk and to
minimize damage, I didn't want to drill holes for the cables. I was
able to remove a bottom panel but then I needed extensions for my non-
usb mouse, non-usb keyboard and monitor. The extension cables for the
mouse and keyboard were not a problem and I believe they come in some
decent lengths.

The monitor cable was a different story. I bought a "standard" monitor
extension cord at Best Buy and my video quality sucked. I did a little
internet research and found that I needed to use a shielded coaxial
extension cable in order to maintain good quality. Just as an example,
this site sells them for $13 - $80, depending on the length you need.

All this said, I think sticking the computer in a remote location may
not be the best idea, for all the reasons so many others have
mentioned.
