"Don't speak to me or my son ever again" 
The Phanteks Enthoo Pro 2 is an absolutely massive chassis! It can be configured to have a full ATX motherboard in there, and an additional Mini ITX board.
Anyway, this is my new server (in the Enthoo Pro 2) dwarfing one of my previous main hypervisors, now my secondary (and currently running this instance) in the dusty Fractal Design Meshify C case.
Started with an old X99-based rig in a busted up old case, now we're here. Gosh my server setup has gone through some major changes over the last six years. 
@corrupt@computerfairi.es Absolutely, but I'd want more cores (a nice v4 Xeon with 28 cores and a higher clock speed would do). 40 PCIe lanes is pretty sweet, and I'd be sure to make use of most of them.
