The purpose of a machine is some selfhosted stuff I have in mind, plus occasionally some working on it, as its attached to my home-office shelf, and close to my keyboards and displays.
So I have an old dell optiplex 3050 mini PC, which I am trying to upgrade dropping off the original HDD, and putting in some high capacity SSD as a storage, with the NVME disk as a OS drive. I want to use it as a personal server to serve some selfhosted tools such as nextcloud, some web pages etc. Yet I want to use it as a desktop from time to time, since its anyways attached to a monitor, so sometimes I will maybe be using as a normal work.

What worries me is if I install PopOS desktop, will it be maybe overload - does decreases the hardware usage in some idle time, which I presume server or raspberry PI OS is doing. I am cheering for PopOS as I am already using it with my laptops and have zero issues with hardware or updates.

Should I maybe use some other desktop instead, maybe some lightweight WM?

Thanks!
