I think I can squeeze things down a bit to make it fit and I REALLY want
to get an SSD.
I don't know, if this would be an option to you, but if I were you, I'd
consider a smaller SSD in combination with a bigger HDD.
Somewhat simplified, my partition scheme is /home on HDD and all the
rest (including /var) on SDD. From my experience, using this scheme, a
128GB SSD is way more than sufficient for Fedora. A 64GB SSD would also
work, but then diskspace on SSD will be tight - Certainly, YMMV ;)

on an SSD? The major users there would be BackupPC and all the
chroots/cache for mock packaging builds.
I've been doing this for years with any problems (I don't use BackupPC,
but am heavily using mock (on SDD)).
Absolutely get a *quality* SSD. I've had a Samsung 830 since they were
new and use mock and got and more on a frequent basis, with no ill
effects.
I share this experience. I have a Samsung 430, which still is in daily
use today (32466hrs (3,7yrs) power-on-hours) and so far has not exposed
any issues (fingers crossed :) ).
Even if life expectancy were half that of a spinning drive instead of an
order of magnitude more, I'd still get one for performance reasons.
Fully agreed - I would not want to work on systems without SSD, anymore.
They provide elderly HW with a performance boost and "liveliness", which
may easily extend a system's life-time by years.
If you had an SSD on this system before, I wouldn't expect you to be
satisfied with a HDD-only system.
