... unfortunately as you say there's no way of telling, as they don't give specific details anymore (which perhaps begs the question - why not!
)
Complacency?
All it took was a phone call to the Medion tech guys and they told me everything I either asked or wanted to know, including the make and model number of the MB without any problems.
If you go to buy a new car, do you not,
1) Take it for a test drive.
2) Look under the bonnet (regardless of what we know) not forgetting to give at least one of the tyres a good kick.
3) Make sure the boot is big enough for what we want.
So why would I not be entitled to know what's either inside by make or model of my possible new PC.

edit:
Just received the latest email from Aldi/Medion.
If you scroll to the bottom of the Medion PC page, there is a further link to a few more specifications of the unit, although I don't really think they are that much more informative.
