Any handheld pcs that do not have a battery and has ethernet port (Or a usb port were one can get a usb to ethernet adapter)? and still have a few usb ports available for a headset and keyboard/mouse.

Would prefer one that came with windows or linux were I can flash windows or mostly any linux distro on it. Do not care if it has high specs since I plan on connecting to my main PC and streaming from it using moonlight.
