One use of these old laptop/netbooks is to have an always on server that can even survive a power outage of a couple hours (due to the onboard battery).

As others have mentioned, the RAM is really low for a desktop but perfectly fine for running a FTP/File/PiHole etc and are usually more powerful than a RaspberryPi.

They also have multiple USB A ports if you want to add storage, ethernet etc.
