Thanks for all the replies. My intended immediate use would be a spare 40gig Maxtor, which I would use to back up both computers. However things may change, that's why I'd like to get something that could also take a DVD writer. The Mac has only a combi drive. My first choice would be another NEC based on good experience with the 3520 in my PC.
Stroppy, I'm in the USA, can find no indication that the Ritmo brand is available here. Anybody have a favorite that's available in the US? Or is Ritmo possibly marketed under another name here?
