I’m a fan of old iMacs orphaned by Apple, and finding 32-bit Linux distros as workable alternatives to hardware obsolescence. Both Ubuntu MATE 16.04 and Peppermint 9 run on my venerable machines…

I was also an OLPC G1G1 participant with both an XO-1 and an XO 1.5 HS, so have a limited familiarity with (very old) versions of Fedora.
