Turns out everything is cheaper online ...
Not a lot of changes from the previous configuration. I think I made a final decision on the case, and chose what I think are slightly more expensive but better power supply and RAM.
Unfortunately Mindfactory.de doesn't accept credit cards, so I'm still not quite sure how to pay for this ...
