My PC is 17 ears old. Although I think only the case and two drives are left of the original build. It recently got upgraded again with an Intel Core i9 and 64Gb RAM. Upgrade I'm most torn apart over is the ortholinear ErgoDox EZ keboard, because after acing the layout, using anything else really throws me.
Also just gave away the remaining one of two 24" NEC flat panels I bought 17years ago. It still works.
