you can use the chasis as a heatsink, so it means that less cooling and ventilation is required, which means that the chasis can be smaller.
my only concern is the weight of the iMac though. shoulden't be too heavy i guess.
my only big request is that they use a the MXM graphics installation system.
having an iMac look like a cinema display would be sweet, but it starts getting into the professional design though, the consumer market used to always have computers with white plastic (imac g4, imac g5, ibook g3-g4, macbook), and the professional market used to always have a kind of metal design, like the powerbook, macbook pro, power mac, and the mac pro.
because of this this is a bit unlikely.
The whole plastic = consumer / metal = pro argument has been argued
ad nauseam. The mac mini is half-half and the shuffle and apple tv are aluminium as well. Whatever the new iMac is, we'll see soon enough. And for all the people saying "
ewww, I don't want a metal iMac, it'll look terrible..." &c., are you forgetting that this is Apple you're talking about? Whatever it looks like, it's going to look good, ok? Stop complaining about something you haven't even seen.
However, I do think a new MXM card is likely, and I sure as hell hope that it's the way that Apple goes. Why? Sure, a desktop card would be nice, but if the new iMac uses an MXM card, (let's say the 8600) then there should be nothing to stop someone getting one elsewhere and installing it in the previous gen iMac. This
forum thread details the efforts of a guy who had opened up his iMac and put in a new MXM video card, physically, it fit, but without the drivers, it wouldn't work at all. (In the latest posts someone says that they're going to try with the new MBP card, but they haven't received it yet)
I've been waiting for 6 months for a new iMac to switch to, purely because I don't want to get saddled with an old video card. (I like to game). But if Apple releases a new iMac with a new MXM-based video card, and, more importantly, the drivers for it, it means that gamers will be able to see the merit in moving to Mac - in terms of gaming, upgrades to processors, RAM, &c. aren't necessary all that frequently (with the exception of
Supreme Commander, there isn't a game I've come across that I can't play on my 4 year old AMD XP 2200 with 1GB of RAM.) upgrades to video cards, on the other hand,
are necessary with a somewhat greater frequency (I most definitely wouldn't be gaming much today with the 64mb Geforce 2 that I originally had in this computer). So if Apple makes it possible to upgrade an iMac video card (N.B. - That's
possible, not necessarily
easy.) then they'll have a much greater appeal to gamers.
