I've never bought one of these all-in-one desktop systems so I thought I'd come to the forums to ask for advice. My 5 year old XP desktop is finally on its last legs and beyond upgrading the HDD or memory, can forgo the ability to pop open the case and modify the system as needed, given the price of a Mac Pro. I need a good desktop system to serve as the hub of a home network (Aiport Express, WiFi printer, Slingbox, a MBP, a Macbook, an XP laptop, and a wireless web cam). Frankly, I'm not even sure how much it will be used on a daily basis. When it is used it will be for web/home office/some gaming (we are not hard core gamers)/sharing media files/amateur photographer stuff eventually. I haven't taken the plunge with Aperture yet (need to get a better camera 1st). No major video editing stuff other than home movies of the kiddo walking for the grandparents. I'd like the 24" for the screen size and have thought about the 2.8, but figure the 2.4 ought to support the above needs. There is the part of me that subscribes to the "buy as much as you can afford" and would consider the 3.06 since that's the most the system can ever be. Having said that, I don't want to spend money I don't have to, especially if I don't NEED the extra horsepower. Thanks in advance.
