The most sleek and slender All-in-One computer lineup we’ve seen to date is now available for purchase through Apple’s (AAPL) online store. The new iMac, which was unveiled during a press conference late last month, features an aluminum and glass enclosure that tapers to just 5 millimeters thin at its edge. Powered by third-generation Intel Core processors, Apple’s late-2012 iMac lineup starts at $1,299 for a 21.5-inch model that comes equipped with a 2.7GHz quad-core Intel Core i5 processor, 8GB of RAM, 1TB of storage and an NVIDIA GeForce GT 640M graphics processor.

The 27-inch model starts at $1,799 and includes a 2.9GHz quad-core Intel Core i5 processor, 8GB of RAM, a 1TB hard drive and an NVIDIA GeForce GTX 660M GPU. 21.5-inch models are available to ship within 1 to 3 business days of placing an order while the 27-inch model will ship within 2 to 3 weeks.

A report from earlier this week suggested that difficulties with the manufacturing process may keep Apple’s new iMac lineup in short supply until next year.
