What system to recommend for fast.ai development?

I’m disabled, but that hasn’t stopped me from learning about Deep Learning, and then the other night I discovered fast.ai teaching it from the top-down, and after using a free hour of Crestle GPU time to explore the first project in the fast.ai lecture series, I’m hooked on their world class AI engine, but I need a new system to support it, and that’s where I find need of compatible NVIDIA GPU system that can also be recommended to other poor students wanting to immerse themselves in a technology I could only dream about when studying neural networks in 1996.

Have you tried any of the free online courses through the NVIDIA Deep Learning Institute (DLI)?
