I have already got a guy off the board lined up, he just dosent know what would be fair the charge... I also dont have the slightest clue on how to install everything and wire up everything inside the CPU.. I figured it would be better left to someone that knew wtf they were doing.
Well when I build them, I take the time to install all software that will be needed (both system and application software), and fully update/patch all software. That plus HW installation time, and drive formatting, means it usually takes me several hours. So I would think $50-$100 would be the minimum.
