The details for the ProLiant DL380 Gen9 will appear here once data migration is complete. VMware Horizon (VDI) will have to wait for a future phase (if implemented at all). The current state of self-hosted VDI is Windows-centric, with second-hand support for Linux and no proper support for macOS.
The planned software/VM configurations have been moved back to the LTT post, and will be changing often for the foreseeable future.
Product links and details can be found here.
ESXi itself is usually run from a USB thumb drive, but I have a drive dedicated to it. No harm done. A small amount of thin provisioning/overbooking (RAM only) won’t hurt. macOS and Linux would have gotten a Radeon/FirePro (ie., Rx Vega 64), for best compatibility and stability, but market forces originally prevented this. Windows 10 gets the Audigy Rx and a Titan Xp. The macOS and Linux VMs get whatever audio the Titan Z FirePro S9300 x2 can provide. The whole purpose of Nextcloud is to phase out the use of Google Drive/Photos, iCloud, Box.com, and other externally-hosted cloud services (Mega can stay though).
There are three other mirrors for this project, in case you're interested in following individual conversations from the other sites (in addition to this thread).
P.S. Out of all the sites that I've ever used, this forum has one of the best WYSIWYG editors I've used in a while 
Kudos to the devs!
