Lenovo has announced a new entry in its ThinkCentre all-in-one line, the ThinkCentre Edge 91z. Aimed at small and medium-sized businesses, the system measures just 2.5 inches thick, offers a 21.5-inch LCD display, and packs a lot of power—up to a second-generation Intel Core i7 quad-core processor. The 91z supports up to 8 GB of RAM, and will be available with SSD and hard drive storage options, integrated Wi-Fi an optional Blu-ray drive, and discrete ATI graphics with up to 1 GB of dedicated video memory. The 91z also packs built-in speakers, a 2 megapixel webcam, six USB ports, Windows 7, and a 6-in-1 card reader. The ThinkCentre 91z should be available in July through Lenovo’s business partners with prices starting at $699.
