Well what of an open source testing rig similar to the setup incoherent made? We provide CNC drwgs and circuitboard schematics/parts lists/etc? We provide test results for a few reference blocks? Like the innovatek system but with better parts? In some ways this is actually easier than testing with a real CPU. And with a single platform then we have the ability to write detailed directions and usage notes too.

The problem I see there is what happens when a measurement is out of calibration? It's very hard to make this into a black box that'd run for years.

And if you send people to ebay as a start for surplus/used parts with no experience then I think they're doomed anyway.
