This is always difficult, because I don't know your situation, but if that's the only reason for choosing something vital like your mobo's chipset, I'm not sure it's the right decision. How often do you plan to install Windows? Even if you don't want to put a floppy in the case, you can just hook one up for the Windows install if needed. I read good things about the Asus P5WD2 (with an Intel 875P chipset, the perfect mate for a Pentium D). You'll want to combine that with an ATI videocard though, because it's laid out for Crossfire in stead of SLi. If that gets too expensive, you can also look for a board with Intel 845P chipset.
Also, if you just tuck away your PC out of sight under the desk and never work on it much, a standard case may be OK. Personally, I hate these cheap and rattly boxes, but then I tend to open them up a lot and tinker about with the internals.
Some people may also advise you to choose Corsair or OCZ memory, but I know MDT and Infineon are more common choices in Germany. The Shop1 PSU may not be the best choice either. Tagan has a better reputation, but that's changing with their latest models again (not as good as they used to be).
Or just wait for DiiZzy, he'll know what to do.
