Plenty of work lies ahead for the user. First the motherboard has to be removed and, in the case of Socket 478 and Athlon64 processors, the retention module must be first taken out as well.
Then, a new backplane is attached, which Asus calls the "H-backplate" based on its shape. Foam padding protects the motherboard.
Now things get fiddly. Four screws are inserted through the H-backplate and screwed into cylinders from the front. The choice of cylinders proves difficult. The terms M3x10 and 5-M3x18, for example, won't mean much to anyone who isn't a trained metalworker.
Both the metal plate and the foam padding under it must be held in place when tightening the screws. Once all screws have been fitted, the board can be turned over again.

Each step is well explained; without a manual things would be very tricky.
