I wasn't saying that they're different components. I've seen some of the US made junk over here. I was referring to the build QCComplete and total utter bollocks. Made in China like most things.
The innards of them are identical to Windows PC innards. QC'd in the same Intel motherboard factory for example.
I'm in that industry by the way (as you know) and have far more knowledge of it than most knackers who like Apple stuff over PC.
Note : I have an iPhone by the way. Built by Foxconn in China.
