I was so pleased to unbox this machine and get to work.  It worked right out of the box, did everything I needed it to... until it didn't.So from early July of 2020 all the way until... November, 2020.  This machine was a beast.  Then it just sort of stopped powering on.  No problem, I'm an IT guy, I know how to find parts and replace them.  So I scrounged up a new power supply.  And when I got into the guts of this machine, holy mother.... The case for this machine looks like it had been rescued from a flooded basement.  The old power supply had corrosion all around it.  It still tested fine, but it wouldn't power the system on anymore.  The only place I saw actual rust was on the case in front of the intake fan, so... I guess that's not the worst?  But now, even after swapping out the power supply - the system took so much effort just to get it to boot up again, I had to reinstall Win10 several times, and even now it will spontaneously reboot whenever it gets a hankering. I'm tempting fate by spending so long tying this up.I've run all the thorough diagnostics, and strangely enough - if given enough time, everything passes.  Which means the problem is either the RAM or the motherboard itself.  But, in all honesty - I should have just bitten the bullet five months ago and purchased a new machine.  If anything like what I've spent the last few days doing to this thing had happened on a NEW computer, I'd be neck deep in a warranty replacement by now, rather than off shopping for a new computer and waving goodbye to the $400 I dropped on this thing (yes, I'm accounting for the replacement parts, because that's also going into the electronics recycling with everything else I can't salvage from all this.)
