I have to move thread and I based it on these criteria.
Someone who is making a a complete new build or at least change most of their stuff inside. Change of mobo and CPU and GPU will qualify. Anything less will be treated as upgrade.
The upgrade which is not significant enough to be classified as new build.
Bought from some company or some one already build for you or participate in less than 50% of the the building process (building process include the initial putting together and OC afterward if OC'ed).
