I also think selecting parts is limited by the fact that there are so few manufacturers. Processors these days mostly come down to AMD or Intel and nothing there is transparent or audit-able. "trusted computing" and backdoors make even your hardware suspect.

There are capable desktop computers with open hardware, down to the silicon: you just have to pay for it.

For example, for $4k, you can get this with specs roughly equivalent to a normal developer machine: https://www.raptorcs.com/content/BK1SD1/intro.html

Actually, for about 1700 you have the Blackbird BK1B01 mainboard + cpu from Raptor, with 4 cores, 16 threads: https://www.raptorcs.com/content/BK1B01/intro.html

I bought two of these last year and they're great, stuff your own memory in there, add some storage and off you go.

Edit: clarified that this would be a mainboard + CPU.

And the cool thing – it looks like there has been some interest[0] in supporting Power for WINE.

Not too shabby looking! Thanks for the link

Neat, should be on the front page.
