My room is at the end of the house where the AC barely reaches and lemme tell you, my room gets hot. Im thinking about putting my comp in the basement and running cables through a chute we have in the wall directly to the basement through the house. Im wondering, what is the maximum lenth of the following cables in order for me to do this:

DVI
VGA
USB

Give or take around 50ft I need to do this. Thanks.
 
I know they sell 50 foot VGA and dvi cables, i think USB can only hit 25 feet, unless you get a power usb, not sure on max lenght of that
 
DVI - depends on quality cables. My guess is you could get away with 50 ft. Look here. I have personally used the 25 ft ones with no problem.

VGA - 50 ft should be no problem. At my work I design aircraft avionics simulation labs where we must duplicate aircraft wiring, including length. I have tested VGA over 50 ft.

USB - according to spec the maximum is 5 meters (about 16 feet). That is mostly limited by wire size (especially on the 5 volt and ground wires... smaller wire = more voltage drop), how well shielded the cable is, data transfer rate, and whether you are looking for it to be functional or whether the signal voltages and waveform conform to spec. As long as you use large gauge wire, it is well shielded, and you're not using 450Mbps maximum data rate... you could probably get away with 50 ft. I haven't tested it though, so thats just my guess.
 
Might want to take a measurement. Each floor is roughly 12 feet right? Even if you are on the second floor thats only 24 feet. (est.)
