New to Sam460ex

Not explicitly a Hardware post as such, but unless I'm going blind (which isn't outside the realms of possibilities) I didn't see an actual Introductions forum.
I find myself in here as I have bought Hans' old Sam460ex system, and being fairly new to AmigaOS4, I find myself currently trying to navigate the Radeon driver situation, while hunting the 2nd hand markets for a suitable card. I think I've roughly got my head around it lol.
Expecting the machine to be here early next week? Then the fun can begin
