> Preferably a Linux non-laptop. You've made this really easy on yourself. Cuda really isn't very picky once you get an NVidia GPU in it. And even a generation old mid-range NVidia GPU will give you plenty of compute performance to keep you busy for a long long time. And when it no longer meets your requirements, you'll have a very good idea why, and what your bottlenecks are. Shop just like you would for any other Linux non-laptop, just with the requirement of an NVidia GPU. My only other recommendation is to steer away from items marketed too strongly at the performance gaming market, as they are sometime clocked beyond their reliability range.
