My Dad has tasked me with finding him a laptop to replace his desktop now that he's on the road permanently.

My requirements:

Intel 11th Gen CPU or newer
Upgradeable RAM (or a minimum of 32GB soldered)
Thunderbolt 3 or newer
At least one NVMe slot for his existing 4TB SSD

Not too worried about screen size/resolution as he will be docking it to a 32" monitor in the caravan 90% of the time, nor am I worried about dGPU as the most GPU-intensive thing he will be doing is editing photos.

Hoping to find something for around the $500 mark, or happy to trade for the desktop that the laptop will be replacing

I'm located in New Plymouth, and Dad's home base is Pahiatua, so can collect from anywhere between or pay for shipping.
