34 The x86 parts are slowly going out of stock to the point where they
35 are expensive *when* I have found them. The TALOS 2 is the cheapest
36 POWER system available, but is still many thousands of dollars more
37 than a consumer computer (though much higher performance). ARM based
38 computers are not comparable in performance to common consumer
39 systems. Self hosting on a performant ARM processor is not a
40 reasonable proposition. High dollar ARM servers have closed
41 motherboard firmware.

43 Sure, if you devote all of a good salary's disposable income to a
44 mostly open hardware computer you can buy one. Most people don't make
45 that much. The bigger issue than that is all main manufacturers do not
46 want to remove their backdoors, and so ever so slowly, there will come
47 to be absolutely no choice at all, even for inordinate amounts of
48 money.
