I would second the motion to be careful and give it some thought, I did my first mod sucessfully on a kT7 and It was doing fine but one day I read that a change in resistor would give me more voltage. While in process of cutting the old resistor off I moved the wire connected to the (bc155
area) one too many times and it pulled everything out including the original solder pad., the board was ok until I kept screwin with it till i killed it. Later I ordered a KT7 raid and after a few weeks i just had to monkey with it...well the solder process went very smooth I thought and put it back in the case and has never booted since, I have no idea what went wrong, I do remember that I was trying a different resistor than the 30k that had worked before ( I had read on a forum somewhere that reducing resistor would yeild more voltage) anyway its dead too and all mine are now MSI unmodded
And I have never dealt with overclockerz store so i will take the word of those that have.
