A Mac Mini with M5 Pro, half the memory of a DGX Spark, half the disk of DGX Spark, and no CUDA, is already more expensive than a spark. The Spark runs Linux natively, has a tiny form factor, and is usable as a general purpose computer.
I use a DGX Spark with NixOS on it as my daily driver and it's fantastic.
