Thin Client solution?

What is your favorite thin client? I am currently using my Samsung in dex mode connected to a monitor to access my VM, but I am thinking of building a cyberdeck and would like to start looking at components to use.

my first idea is just have a hand wired keyboard on a acrylic that hides essentially a usb hub with a portable battery and a slot where my phone can slide in to use dex mode, then have a small portable monitor but it would also be kind of cool if it was all usable without my phone, so maybe something like a raspberry pi would be nice
