KVM Extender Reccomendations?

[Alterscape]

I'm currently speccing out a system for video/audio editing work. My current system is incredibly noisy, and lately I've been working with a rig at my university where the tower (a first-gen apple G5 tower) is stored in another room and the cables are run through a hole in the wall to the recording/editing room. I'm likely to be living in apartments for several more years, so drilling holes in the walls isn't an option I can count on, but I hope I can at least stuff my tower in a closet and run a long KVM cable out to the desktop.

I'm not 100% certain of my final configuration, but I'm fairly certain I'll want the ability to run at least two DVI cables, USB mouse, PS/2 keyboard, and several channels of Firewire and USB for peripherals (DV deck, audio i/o interface, external DVD drive) to the PC, which may be 15-20 feet of cable away from the KVM.

I hit Google for reference but the first few hits seem to be expensive boxes that use fiber optic or cat5 cable to move the KVM extremely long distances. I'm not looking for anything that extreme.

Related question: If I'm looking at the USB/firewire controllers on a G5 powermac or a hypothetical Intel-mac equivilant, I'd be better off from a speed/bandwidth perspective running as many extenders from the tower to the desk as there are ports, rather than running one of each and attaching a hub and/or daisy-chaining, right?

Other related question: Does anyone have any thoughts on the best place in an apartment to put a noisy PC? Another room would be best, but I'm not sure I'll always -have- another room. I mainly want to kill the noise without overheating it -- going to a fan-less PC isn't really an option because I need the high-performance (and high-heat) components. I'd rather not water-cool and kill the warranty on the new mac I'll be buying, cool (both literally and figuratively) as that might be..

I've seen people install their computers into their desks to reduce or kill the noise factor, but the obvious problem is overheating so like what i plan to do as well is chop up the desk a bit and install some 120mm fans from an extra PSU i have lying around to give the box intake/exhaust from the rear and sides to reduce noise, you can also do this from a space away from your desk, but if you enclose it you will need to give it ventilation.
