That sounds about as dangerous as unlocking a Palomino core Athlon XP. XActo Knife + scotch tape = not gettin fuckin near any of my PC hardware. Too risky if ya ask me! I'll all about some BIOS flashing (I hear the 5900-to-5950 Ultra works well...I know two people that flashed their 9500 Pros to 9700 Pros rather easily as well), but when ya have to physically fuck with the hardware, I basically draw the line.
