I have been scavenging parts here and there for this for a while...
16GB DDR4 + Intel 6-core old stuff.
Haven't yet ordered some cables for the SAS controller, but the aim is that, after I am comfortable with cooling this thing without too much case cooling. Ideally, without a case.
The IO is the most important part. And that's the focus, obviously. Will be all SSDs...
Would love to do a ALL passive node, but I think this will not yet meet the standards. Maybe when I get the ARM mobo I want, that might be the opportunity.
This was to test
