Definately underestimating it, an old RPI can easily run a full on desktop OS, maybe not like a bleeding edge KDE with all the visuals turned on, but XFCE LXDE, etc… would run fine, libre office and basic IDEs…
but yeah absolutely zero reason to think you’d have even a wink of trouble running terminal based stuff.
I mean if it’s already imaged at some level with raspbian or something, technically it’s most likely already set up to do the concepts you are looking at without needing to set up a new distro.
So to add anything up to date you would probably need to get a micro sd reader… here in the US you can pick one up for like 5-$10 at walmart, so we aren’t talking a huge investment.



X2goserver certainly is an option there. not too complicated to set up, or VNC is another option. As always there will be a bit of screen lag when sharing a gui over network.
and yeah as someone else pointed out there is also the option to run x applications from an ssh client if you enable it. now I will admit I don’t think there’s a huge amount of utility, more pointing out though it’s most likely you are either drastically underestimating the power of a raspberry pi, or maybe overestimating the resource overhead of linux distributions.
The linux world doesn’t quite have the mysterious resource usage creep at nearly the same scale as windows a slim but still with gui setup can still run in under 100 mb of ram.
Leaning on the extreme low end assuming you were a generation behind… the raspberry pi 2b+ came out in 2015 with 1 gb of ram. So yeah, while I can’t really name any gui applications that might be desirable to use in that way. IE it could be a decent web browser station, or kodi media player if hooked up to a TV etc… I would imagine lag from using a gui application accross would easilly remove any advantage that you’d get over… well just running the probably existing version for the windows PC that you are likely remoting in from.
