32G is more than enough for Qt5.  With that much you could make a
tmpfs of perhaps 8G for /tmp, and that may help a bit with speed,
especially when large tarballs are being extracted.  You must
remember to move anything out that you want to keep before rebooting
or shutting down though.

Added to that, have you read my README.ccache and tried setting it up
in the system?  You will save a *lot* of time on rebuilds with ccache
working.

Hope this helps.
