I moved my homelab into a colocation rack (proper DC deployment with redundant power) a while ago. Things have been running smoothly, and a few favorable 2nd hand deals later I now have 128 cores (Epyc Zen 2), roughly 1TB of RAM and several dozen TBs flash and spinning storage running idle.

It's all on spare enterprise-grade hardware (15th generation Dell PowerEdge, redundant SAS SSD/HDD arrays), interconnected with 25G. Uplink is 10G. It's utilizing number of external IPv4 addresses. Located in germany. Properly firewalled, monitored (including iDRAC data) and segmentated into appropriate VLANs.

My thinking: somehow utilize this to offset colo costs for my homelab (same rack, seperate HW). Desired target would be a monthly high three digit revenue stream after taxes.

I know that this stuff comes with extra liability but I think I'm prepared for the kind of work. Currently a Senior SRE, used to be a Sysadmin for MSPs. I would probably need to create some sort of small business in germany. And do KYC in order to avoid breaking my providers ToS.

I've already tenatively mentioned renting out compute on Linux VMs with dedicated vCPUs in several public IT spaces, but feedback has been modest.

Another option might be application hosting for small-ish businesses. Depending on the kind of requirement I could half allocable CPU and memory (each half allocated to one HW node) and run a HA setup. Plus offsite/disaster recovery contingencies.

My main point - or question - would be: Is my line thinking sensible? Are others running similar platforms, and what's the experience? I'd be a one man show and want to keep this a side hustle.
