that is a awesome seller...dealt with him a ton of times for stuff...
Got the GPU a week ago and upon inspection i noticed that it had residue of thermal paste on the top.
When i inspected the bottom i didnt see any signs of reballing however so i think its new as he described..
(Both sides inspected in microscope with 6x magnification)
I sent him a mail about it, explaining that im just curious as to why there is thermal paste and assuring him that i wont claim a refund nor give him bad feedback, but no reply yet..
Anyways, ive reballed the CPU and soldered that and the GPU today so we will see how it goes..
Had no issues with dog-earing once i started using the APR5000 instead of the IR station from Metcal
Ah well, still need to get my hands on a broken box so i can drill holes and make a proper thermal profile. Once i do ill post it here in case others have an APR5000 and wants to solder xboxes..
