@silverwizard yeah. Honestly the only way you'll get numbers on a single server is Dell/Lenovo/HPE/etc. and it'll be a 9+ month wait unless you have a multi-million per-quarter relationship.
MOQs on ASRockRack and Mitac/Tyan are... prohibitive to say the least. The delusional are simply buying up all the production, continuously. I can get singles but I only do full cab HPC stuff these days.
