"Karthus needs the greatest mana pool he can get, so he needs ROA and Archangels."

No, he doesn't. Tear is sufficient for Karthus' mana needs.

"The item that scales the most with those two is rabbadon's."

Not necessarily.

"Void staff is essential as always. "

Depending on enemy MR, but in 99% of games yes. In fact it's better for your damage than Rabadon's a lot of the time, particularly when you consider their relative costs.
