If you decide to build up your system from the miniME it's not hard.
The full system will be there for you, just add your applications via Synaptic, found in PC>Software Center
First update your install with Synaptic by;
-reload, mark all updates, apply, apply
Then the fun begins.
use the synaptic search button to find a web browser, check the box on the left to install, apply
Office suite, install lomanager (that is lower case L)
Run lomanager from PC>Software Center
Since you have a linux background you probably know the apps you like & can search them out via synaptic. Though your RH desktop was Gnome & your miniME is likely KDE. A gnome version is available if you prefer a familiar environment.
There are a couple of threads of the apps folks here add to build their miniME.
Let us know your progress.

oh, and follow old-polack's advice for best results.
