I have 2x Dell R720's and a consumer-grade i7-3770k box, some shiny ubiquity gear mixed with ugly network gear, and a Synology DS918+ for personal storage.

I tend to lean on straight up Debian linux for most things. One of the R720's is a VMWare ESXi host, the other is a k0s box running on Debian Buster, and the 3770k runs Fedora because I wanted to taste the redhat/dnf fruit but I am diehard Debian.
