You know me, I'm not very demanding in terms of computing power, any modern laptop would feel like a supercomputer to me — even quad-core i7 still feels like a decent machine for building stuff. I'm used to be on low-powered and old equipment.
I think all computers I use daily could fit in a medium-sized suitcase, in fact I sometimes do take this stuff with me when I have the opportunity to live in the country.

I usually don't take boxes I use for hosting stuff, I could — these aren't big either, but there's no need to, they are pretty autonomous, the most they need is being restarted after the power outage, I can do everything else, including the filesystem repairs remotely.
