I think my favorite is still the one that got me all started on this a couple years ago: Anniversary LGA2011 build — Serverbuilds.net I built that (dual xeons 128gb ram and 9TB array) and started into a fun world of self hosting and have learned a lot (and tried not to buy into tooooo much unnecessary stuff).
Since that’s not necessarily in the forum… I think the HP290 stuff has been my go to forum post… I’ve got a couple 290s as project builds and now a 590 on its way. [Official] HP 290-p0043w Owner's Thread
