A friend of mine recently bought a new G5 Power Mac (dual 2.3GHz). When he bought it, he had decided he wouldn't want the wireless upgrade -- though once it was setup at home, he decided wireless might not be so bad afterall (a hem, aka didn't want the trouble of routing network cables to his new home office haha). Anyhow, I told him I'd look into what his options were.... It's my understanding the newer Power Macs have PCI Express slots instead of the old PCI slots. I'm guessing (correct me if I'm wrong) that means that regular PCI cards won't work in the Power Mac. So from what I've read so far, the options for him will be an Airport Extreme card, or a PCI Express-based wireless card (if there are such things of course - I couldn't find any yet... if there are some, I'd appreciate any recommendations). Having just bought the Power Mac, and in the process of buying the other typical add-ons (RAM, external hard drive, etc) he's interested in saving $ if possible. So far as a wireless router, I was considering recommending the Linksys WRT54G for him, since it's pretty cheap and it has worked pretty well in my experience. I know an AirPort Extreme Base Station is cool, though probably out of his price range. If you have some other suggestions, I'm all ears Thanks in advance you guys!
