Maximum PC

I have placed my PC on top of my desk about 2ft-3ft from my subwoofer which is placed on the ground for years and nothing has ever happened, actually one of my WD hard drives died a couple of years ago, but I don't think that's related. I need more room on my desk so I want to move my PC from on top of the desk to the floor, but it will be right next to the subwoofer. When I mean right next to it I mean an inch or two next to the subwoofer. Will that be safe to do so? All this time it has technically been next to it, but elevated and farther away. This time it will be on the ground with the subwoofer and very, very close. There is a SATA hd, and a IDE hd in it if that matters. Also, if it makes any difference, my case is a Lian Li PC-V1000B and my speakers are Klipsch Promedia 4.1's.

I have had my sub within a foot of my pcs for the past 15 years and never had a problem.

Nasty

The only issue I've had with my PC tower next to my large ass bass has been too much vibration, causing the SLI bridge to vibrate loose. But I listen to very loud, thumping music constantly on max volume with bass on full.

Good to know, I have a down firing sub that is very loud. Know I feel better that I plan to put it on top of my tower.
