ThinkSecret believes that the next generation iMac is in line for release in August with a brushed aluminum enclosure at only two inches thick:
The elegant new enclosure will somewhat resemble the current white iMac but is said to feature a shorter space below the actual display, where most of the internals are housed.
The new iMac is expected to be based on the Santa Rosa architecture and will only come in only 20" and 24" flavors with the 17" set to be discontinued.
Our Buyer's Guide notes that it has been 303 days since the last iMac update.
