heres a pretty good resource, bit of a tangent but i got a ton of shithouse computers with very low ram and i think alpine/postmarketos is the best choice. ive gotten kde, cosmic, and so on running on tons of terribly old computers with it, typically with no more than 1-2gb of ram. its also good for computers with only 256mb or so. after a certain point you need to just load your OS into ram entirely in order to have any ability to handle modern applications on very old hardware, in this case you should consider buying ram for your very old hardware (it comes cheap for the top compatible tech when its 90s hardware) if you like to use it as a sort of display piece for visitors to use. there are a couple of distros in that list that can handle being stored in ram. but obviously youre a bit different because you can just run it all on a vps. still probably best to go with alpine despite the operational differences
of the mainline fully featured modern desktop environments i feel cosmic de works the smoothest on old hardware, strangely enough.












crypto is useful too, without monero i wouldnt have hrt. place i live in is a shithole and doctors are highly restrictive and far too expensive
but monero is the best one in terms of privacy and it is unprofitable to mine it unless you have the latest and greatest green processor
