Next-gen brushed aluminium iMac in August?

The rumor cycle continues to turn, with the iMac the latest to get the ol' speculation treatment. ThinkSecret says that the next iMac will hit in August, and will feature a new, 2-inch thick aluminium enclosure. The new model will reportedly feature a trimmed down chin -- bye bye Jay Leno iMac! -- 20- and 24-inch screens only, and Santa Rosa CPUs up to 2.4GHz. Before you start buying up metallic-styled peripherals in preparation, you might be wise to take a quick glance at our iMac rumor tag: if the eventual iMac replacement is nothing like this report, don't say you weren't warned.
