# Awesome ThinkCentres
These machines can be found used for about 100-250 usd/eur. Most often found with 6 core cpu-s (8400t/9400t), single 8gb ram sticks and smaller 256/512gb M.2 nvme drive, and wifi configurations.
What is this is good for?
- homelab
- k8s nodes
- NAS/router
- dev/test boxes
Models covered:
- M720q
- M920q/x
- P330 tiny (Same as M920q but with 2x m.2, ie like an M920x)
