New iMac: Is It Summer Time?

It is of course difficult to avoid talking about the last rumor floating around and initiated by Apple Insider.
The new rumor predicts that the new iMac will come during summer time, some day between July 15th and August 15th. As previously reported, the 17" iMac should disappear and iMac models should only be based on 20" and 24" LCD display. But that's not all. The new iMac enclosure should also be redesigned and feature a brushed metal look.
To have disassembled an iMac Core 2 Duo, we confirm that one can not really save a lot of space in the current design; it is well organized and packed already. A metal enclosure will of course improve heat release, allowing maybe to reduce the cooling system to save up to 1 cm in thickness. On the other hand, one could make the new iMac almost looking like a display, by packing everything to get ride of the bottom white band, the larger display allowing to pack everything behind the LCD panel.
So, according to the rumor we will only need to wait for 2 months before seeing the new iMac.
