I can vouch for nostr:npub1r7psmkr4zv93xnal8un6d8hvmpsn5jvhfzn3kk38rfcel6awznks7znspg and his hardware/IT chops. He's helped level up my node / home server / Proxmox game. I'm running two refurbished laptops he sourced for me and two more powerful used mini PCs that I bought once I knew more about what to look for.
