I was looking for a multi-core system to run ESXi on and run multiple VMs for various projects.  This box fit the bill perfectly.The good points:  a:  It's quiet  b: It's fast enough for me,  I'm only running 4 vms currently but they are all running faster than when on my Mac Trashcan (6 core),  that's probably because I was over-committing cores on the Mac.  This box is practically idle at this point  c:  There is room for expansion,  lots of room.Nits:  I removed the 2nd video card since the version of ESXI isn't doing PCI passthrough,  that's not a slam on the box but I removed the card to keep down the power usage.Using a watt meter I am at < 200 watts with all VMs doing light work.  Again I'm not doing any video.  I do hope to upgrade to something that will let me leverage the video cards for machine learning but that's down the road.I did do some testing with Ubuntu (dual boot) - to see what it's like to push all 32 (16 cores + hyperthread) and running the Lammps simulator it's pretty fast.  It's faster than my Mac Pro due to the fact that I can throw cores at the tests.All in all for the price this is amazing.
