Since I would replacing a G3 iMac with this — no screen I can reuse — this gets pretty spendy. I can get a decent flat panel display for a few hundred dollars but at that point, I’m pretty close to a G5 iMac. So I get a faster machine (1.8 GHz G5 vs 1.42 GHz G4), with otherwise similar options, for a coupla C-Notes more.
Why not go the whole way?
