Both the DL380p and M710s are running in a ProxmoxVE Cluster with various containers and VMs.
At the same time, I have the EliteDesk running a Proxmox Backup Server.
My Homelab is connected via a Wireguard tunnel to my VPS, which is how I make most of my services public.
My Thinkcentre is currently responsible for running Jellyfin with an Intel iGPU for Hardware Transcoding.
Aside from that, it's sporting two 1TB hard drives in a mirrored ZFS pool for backups and other NAS shenanigans.
In contrast, everything else I host tends to run on my DL380p, which includes services such as Pi-hole and Unbound for DNS.
Additionally, I also host a PaperMC and Factorio server to play with my friends and a Bitwarden server to host my passwords.
And last but not least, I have a Debian VM responsible for hosting a CUPS print server to share my old Brother HL-2030 USB printer with the rest of my LAN.
As for the R620, it's running TrueNAS SCALE bare metal with three 4TB hard drives in a RAID-Z pool, which is mostly just for hosting my Jellyfin media.
I know the hardware is pretty overkill for it's current use case, but I got the server at a pretty attractive price with all its bells and whistles included.
