Front/Top Panel PortsDavid, one of the things that was not mentioned, in the specs I found for your Acer, was whether it had USB ports available.
Maybe upgrade to a SSD of 150 GB's if you can?i guess i will be able to comment on that(size of updates rolling release) , since my laptop is now a dual boot of Slackware and now Vanilla Arch(instead of EndeavourOS) . Its a bit tight on space with an SSD of only circa 50 gig . The slackware is current but a year old - it will be too much of a jump to system upgrade to release of slackware 15. Slackpkg updates only packages already existing along with manual install of kernel, firmaware and headers.
So my choice is going to be clean install on whole of HD of slackware 15 or if Arch works out delete slackware and stretch partition that Arch is using into the free space created .
With either the jump to a new release or the sixe of updates i guess you just can't win
