Is there any Linux box hardware introduction? Can it serve as a screen for TV or phone?

Without a computer, it is inconvenient for me. I have no computers available because my business has failed and valuable things were sold, including two E5 mainframes, a Legion notebook, and now I mainly want to use the browser on the computer, which is not convenient either. I tried to install Arch Linux on my mobile phone with termux, as well as tigervnc, but it was unstable and would often disconnect automatically, so I thought about installing a box computer to install Linux, using traditional displays or connecting via WLAN on a portable device through VNC software?
