The A70z is reportedly quick to boot and shutdown, a mere 2.4" thick, and can be mounted on a wall to save additional desk space. Its power supply brick is integrated to further reduce clutter, and you can access both the HDD and RAM by removing only two screws -- a nice touch over other all-in-ones, especially for businesses. Prices start at $499, and it ships later this month with Windows 7.
Lenovo's A58e desktop system offers similar specifications in a larger package, including the choice between a Celeron or Core 2 Duo processor, up to 2GB of RAM, and a 320GB HDD. Lenovo claims its new desktop can cut electricity costs by up to 69% per year, and it starts at $349 and will also be available later in the month.
