IIRC the Draco was one of the first AMIGA compatible computers (the other was the EaglePC) and was intended to be a video editing system (think Video Toaster for Germany / Europe but using only MacroSystems cards). It was fairly well received but it was expensive. The link you provide shows a much newer case. The original version was a towered system, much like the C= A4000T.
As others have posted, it did / does not use the Amiga chip set so if a program you are trying to use needs to address an AMIGA specific chip, that program will not run (ie alot of earlier AMIGA games).
