Power/Cooling is not a concern – What rig to build?

I'd like to start off small and I've seen people start with something like a Raspberry Pi and build up from there.

I have access to power and cooling as required and want to build things up gradually from a couple of old laptops I've been using.

But I wanted to start a purpose built and modularly expandable rack of rigs.

Q: What would you recommend for a small space where power/cooling is not a concern and where I can add rig after rig in a modular way?
