Seriously, this trick is extremely easy. Cover everything besides the ram, cpu, and gpu with layers of thick plastic (try painting drop sheets) I then taped it down with electrical tape. Then layered the mobo with aluminium foil, make sure there are no holes or cracks onto (if heat gets in, it gets trapped). I heat gunned on the lowest setting for a minute then high for about three minutes (I began to hear a popping sound, and quickly stopped heating). I pulled away the layers and saw the plastic had shrunk onto the capacitors and other things you don't want heated up. I let it sit open for about an hour, came back put it back into metal cage booted up, worked perfectly -- still does (I didn't think it would work because I didn't see the solder turn yellow or golden brown, everything looked the same -- don't be too preoccupied on the actual appearance, just go for time heating)
