Hi Im thinking of buying a mac mini for my mum. She is using my old PC but its dying. Just today I found two trojans on it! I found an ex-demo mini (Model Number: M9686X/A) for $499AUD. Its the 1.25 ghz combo drive model - 256 mb ram, 40 gig HD, Panther (no Tiger ) with balance of warranty until 27/2/2006. To buy it new it would cost $799AUD. The new ones come with 512 MB RAM!?! Was there an update on the mini sometime that I didn't know about? So basically I could get it for $300AUD cheaper than new but with less ram - but thats ok. My mum isn't going to be doing anything resource heavy. But my major problem is that it doesn't come with Airport Extreme built in! When u buy it from the Apple Store it is an optional extra. Has anyone installed an Airport Extreme card post-purchase? This is what Apple says about it: I have a D-Link wireless router and D-Link modem. I use them to surf the net wirlessly on my PC and my powerbook. So I won't be able to do this with the mini. Would I be correct in assuming that I could connect the D-Link modem via ethernet cable into the mini (with the modem connected into the wirless router via ethernet cable as I do now) and that would solve my problem. But that may also create a problem as it may decrease my wireless area. i.e. when I use my PB in my bedroom it might not be able to access the router because of the distance. Im wondering if it really is worth the money now. Has anyone had an airport extreme card installed post-purchase?
