Basic specs are i5 or i7 gen 8 or newer. 8GB memory minimum and 16GB is better. M2 drive for boot, anything 250GB or larger. Room, power and SATA connections available to add additional drives. Being able to have a minimum of two. That is a more flexible requirement because CD drives can be removed and replaced with platter drives. Worst case, as long as power and SATA connections are available, some Velcro can easily hold a platter drive in place if there's not enough bays as long as there's physical room for it. If you want to use DeepStack, and probably SenseAI in the near future, enough physical space and a PCIE slot for a graphics card. These cards can actually be double thick so physical space is important. Power supply requirements also go up with a GPU card. I'd say 600 watts for some reasonable overhead for a "big" card.
