Once you work in enterprise IDC, setting up home labs is nothing but a liability. Unwanted stuff like UPS, cooling and more bills. I have one Intel NUC running FreeBSD 13 (dual SSD with 32 GB ram and Intel i7 CPU 8th GEN) with one jail and VM. It acts as a backup server for my Ubuntu laptop and MacBook pro. Nightly I dump data to cloud providers for offsite reasons. Finally, I set LXD, Docker and KVM on my Ubuntu dev laptop for testing. That is all. No more FreeNAS or 3 more servers including 2 RPis. I made this change during the first lockdown. They (I mean fun and excitements) went away once I handled all those expensive IT equipment/servers/firewalls/routers/WAFs funded employer ;)
