Ryzen 5950x cpu, 64 gb ecc ram, dual 16 tb drives for zfs, Nvidia 5070 gpu.
Way way overspeced for what I listed, but I use it for lots of video processing, numerical simulations, and some local AI too.
I have a similar subset of this stuff running at my mom's house on a 16 GB ram Beelink minicomputer. With openvino frigate can still do fully local object detection on the security case, whish is sweet.
