I have a p50 or p51, it’s so heavy, just a tank. I think they called it the portable workstation. I have LOVED this thing. It ran any Linux distribution I needed, was speedy, keyboard never missed, it’s in a closet now in headless mode running proxmox.

I have a P50 or P51 and same. It’s a tank but love the thing. Mine is the model before they killed the drop on dock and I prefer that over the USB-C docks.
