At some point this week, I should be transitioning from /r/homeserver to /r/homelab.
Current:
HP DL380 G6 running Proxmox. Dual quads, 48GB RAM, 8x146GB SAS drives. It currently serves as my reverse proxy, tiny web server, document storage, and occasional game server. In the near future, it's likely to have shiny new PaperCut and password manager VMs.
Near future:
Obsolete Xserve 2,1. Single CPU, maybe 16 GB RAM, two 1TB drives. I have a spare drive that should fit. Planning on turning it into a media server given my current media requirements.
Cisco Catalyst 2960G. I don't have much info on this one but the inventory tag was mis-labeled. 24 port 10/100/1000, four dual-purpose 10G/SFP ports.
I have a rack pic but it's a bit nontraditional. The above three machines add up to 4U, which should fit lovely within this monstrosity, since enclosed on two sides to protect buttons from prying toddler fingers:
