Is there any modern day KayPro equivalent computer?

I'm looking for something sort of like the old KayPro computers if you remember them. They were portable, but they were not lap top. The idea is you had like a suitcase, and you could open up the suitcase and there was a computer, but it didn't have batteries. The idea is portability, but more power, and no battery. It would be like a tower computer, but an all in one unit that was portable. I remember Monorail was sort of like that. There are all in one computers but they don't look sturdy enough to carry around like a laptop.
