Not my site, though I’ve bought from him before. The Corne PCBs are pretty popular and can be bought lots of places. I think the username is because he’s active on reddit and answers tech support style questions there.
Alternatively, buy a Corne PCB and make two of them (or a left AND a right) yourself! https://keyhive.xyz/shop/corne-v3

Been using racknerd to host my tiny stupid websites for a couple years, it’s great value for money and a fantastic way to learn sysadmin stuff. I also appreciate that they give a lot of heads up for auto-renewal and don’t escalate pricing on renewal.
