Don't throw it away. Install windows 8, and the last offline version of office you can find. It makes for a great distraction free workstation and a monitor for your android (scrcpy).
Or, you can install and reinstall linux distros and learn the ropes.
You should be fine as long as you use a proper firewall device and access only manually withelisted websites, but it is always better to keep it offline. That said, it can become your next firewall device.
I built it circa 2012 or 2013 and still have the physical win8 disc. I considered futzing with linux on it. The extent of my linux experience is via SSH to a raspberry pi kludging some docker containers for this and that. SSH/linux terminal feels like fumbling in a dark room flipping random switches until something works.

I also have a pixel 5a whose screen doesn't work, but I think functions otherwise. Would this allow me to interface with it?
I think the pixel 5a can be connected to tv through an hdmi cable. If so, plug that and a mouse to setup adb (toggle enable adb and toggle debug permissions, then accept adb host)
