Also forgot if to say if you need a laptop:
The Lenovo G505S with an AMD CPU:
Coreboot with open source init and a few blobs (graphics, fan and power
control) - no ME/PSP.
It is impossible to disable ME, no matter what some companies might say...
AMD PSP is AMD's version of ME present in the new AMD stuff - one has to
buy an older 2013 or before AMD x86 CPU to avoid it generally.
Todays options for *new* owner controlled performance hardware is POWER8
and 9 - x86 is dead and those who claim otherwise have no idea what
they're talking
