Questions about Thecus N5200 / N5550

So I'm thinking of getting either a N5200 or N5550.
I have a couple of questions...
1. Is there a module available for these?
I found this one http://forum.thecus.com/viewtopic.php?f=36&t=3610 - would this work?
How easy is it to setup a Thecus NAS and install modules?
There does not seem to be a guide like the rest so its either straight forward or not
