I have my tower right next to my amp(fender 4x10) and have had no problems. If I'm not mistaking, Your concern it is that the magnets from the amp may damage your computer. I do know that if a strong enough magnet is used you can erase if not damage the hard drive but the magnets from an amp probably won't do that. Unless that is, you are playing in front of a wall of marshall cabs. :) That may be an issue. Other than that I would'nt worry about it.
