What your situation for data backup? You mentioned a homelab and a NAS, are you running regular backups to an off-box store? You could mate it with a few TB of inexpensive USB disk, maybe some software RAID, and use it for off-box backups. Doesn’t have to be fast, just reliable.

Specs like that, you have some options. Virtual assistant, IPCam NVR like MotionEye or Frigate, media server for your car (takes DC voltage, right?), weather base station, ADS-B feeder, smart mirrors.

Or (if you’re in the US) you could repair it and then, if you donate it to a suitable charity, you could take the the cost of the repair as a deduction on your taxes. Probably doesn’t help you that much, but it could maybe really help someone else who needs it.

Or, just wipe it and send it to e-waste.
