DS3 Rev 2.0 + Tuniq Tower 120

[jucestain]

My friend pointed out to me that some people are having problems with the pins on the back of the ds3 touching metal backplate of the tuniq tower 120 (which I happened to see AFTER I installed my tuniq tower...). I already have mine installed and didn't have this problem. I'm kind of scared that if my computer gets knocked or moves that the pins might touch the backplate. I was just wondering... Does this problem effect rev.1 and rev.2 ds3's? The solution I've heard to do is to put some electrical tape over the back of the mobo to prevent them from touching the metal plate. Do you guys think I should do this to be sure or do you think it should be fine the way it is? Oh, one more thing. I remember the backplate from my zalman 9500 being plastic. Does anyone know if any stores sell plastic backplates? Or if zalman would send me one for a fee?Thanks,
