At that size it no longer called a "house". ;)

Well, if you have to take a run from say the garage, to the attic, then
down the edges of the closets to the basement, you can add up quite a
few meters ;-)

Well, Bill Gates doubtless has the problem, but I am sure he has
adequate resources to solve it. Grin.

Not sure exactly what your layout is, but you would like the splitter
installed where service first enters the house. That may change your
thinking about how things will get done. For instance, I had the modem
placed in my basement, near where I could easily access the space I needed
to make a drop from the attic to the router (right next to the modem.) From
there I can easily make runs to any first floor location from the basement.

In your case, you probably want the modem and wireless router in your
office. Patch cable from pc to router, and your done. I'm not sure if all
G4's have wireless networking. If so, I would try wireless from Mac to
router.

If you make the right choices, all of the pieces will fall into place.

Realistically - get wireless router - and implement all the security / best
practices - and you will be fine.

Change the default TCP/IP addresses / network
turn off DHCP
MAC Address filtering
Strong Encryption
Disable SSID Broadcast (more of a security blanket)
Personal firewalls
etc etc
