Please dont scare me LN
I'm an expereinced PC builder and have built all but my first PCs, about 20 PC in my PC building career, mostly for friends and family!
...but building this Athlon system was a nightmare...and that was due to the CPU and the fan seating...I used some artic silver paste on it and all but it was a scare-filled time! ( actually cracked one core during this process

)
Anyway, I'm very hesitant to remove the heatsink to do a summer clean out.....may have to though!
