I have done pretty much the same as you, except that instead of an on-premises 42U rack of stuff, a lot of my personal and family infrastructure lives in a single beefy 1U server (32 cores, 512GB of RAM, set up as a hypervisor) in colocation at a major IX point.
Then there's a set of about six or seven $4 per month KVM VM at geographically distributed offsite 3rd party hosting companies for things like secondary authortative nameservers and such.
And an offsite backup system that mirrors everything on the system in colocation to a medium sized disk array that lives in the corner of a closet in a family member's basement.
