Yes, the third link in posting #52 leads to a page saying that the Cube can take Radeons 9000, 9200 and 9800 Pro.
It can be pretty challenging to install Radeon 9800PRO into cube.
Not only physical modification of card pins, but you need to solve cooling, and finally length of 9800PRO is 190mm and cube outer size is 7.7" incl case = 195.6 mm !! Not much space for installation.
Anyway, the Cube is very nice machine!
