I know that I'm pretty late, but some months ago I tested Rhapsody DR2 x86
on an old Compaq with a Celeron 400 processor and 128MB and Rhapsody ran well.
I had a spare video card that was fully supported (Cirrus Logic GD5436), but
unluckily neither the network card nor the sound card that I have in it were supported.
The applications available for it are very few, you can get Nextstep and OpenStep applications
running but it's difficult as they will often complain about missing libraries or libraries
in different places than where they are in Rhapsody.
The only filesystem supported are UFS and ISO9660, and that gave me problems,
as I tried to transfer files via tar archives written raw on floppies, but it didn't let me do that,
I wrote on the floppy device using dd and then the floppy driver crashed and I couldn't use
the floppy at all if I didn't reboot.
I managed to compile some applications directly on Rhapsody, with its old GCC 2.7.
You can find them here.
It's mtools (useful for transferring files through FAT formatted floppies) and unace
(unarchiver for old ACE 1.x files, compiled mostly for its sake to see if it compiled).
