lol are you sure? On eBay there are tons of cMac Pro cheaper than $1000 and I just need to upgrade RAM, GPU, and or CPU. That's why I estimate the max price is around $1500.
[doublepost=1472231448][/doublepost]Guys, base on what I researched I can get what I want within $1000~1500 and all of them are cMac Pro genuine parts. I don't see any issues of using genuine parts at all and it was meant to upgrade like that.
That's exactly what I tried to point out. You better "buy" a used cMP, but not "build" a new one to avoid that 5 years limitation.
Anyway, "buy and upgrade" is NOT "build".
