it’s an i5 13xxx with 64GB ram and a HBA passed through to TrueNAS with 7 disks on it and a second network card passed through to OpnSense for WAN/LAN
All the above runs in Proxmox and has a bit of room for expansion still ;) This was a 50th to myself to replace an IBM M4 space heater
Yeah, that was the reason I switched from pfsense to opnsense about 4 years ago
