I bought a datacenter GPU that doesn't fit in a normal motherboard, macgyvered the fan with jumper wires, and now I'm running a model that ties with Claude Sonnet 4.6 on benchmarks, all for £200.

      I appreciate the kind words! Until recently, my day job was CAD monkey. I wanted to consolidate the hardware I was cobbling together, found a cheap 8 GPU mining rig and some extra 2020 extrusions to play with.

      The seller for the mezzanine said it followed the mATX mounting hole pattern, (it does but is ~75% in the width and doesn’t use all the points). I have a tendency to overthink designs and kind of stalled for a bit before finally taking the plunge and whipping up these struts. I used some brass heat set inserts to accept the standoffs and everything pretty much went right together lol
