Welcome Nasty!
I am afraid that we will not be able to help you much. None of us owns a MRT NAS.
But there is an
English MRT forum and the
nas-portal which is in German but there is an English corner too.
Although someone has written a
wiki entry at the NAS2000 Wiki
At nas-portal there is a German
post about debian - you could use Google translation
It should be possible to install debian on the MRT DUAL-NAS-E (Giganas) as it is similar to the Raidsonic NAS4220.
