After surveying the low-power computing market and requesting some 15 products, we ended up with the following eight systems for testing in ZDNet UK's labs:

Lenovo ThinkCentre A61e* (compact desktop PC)

Aleutia E1* (mini-desktop PC)

For those products that did not ship with a monitor or have one built in (marked with * above), we used NEC's 15in. AccuSync LCD52VM, an XGA-resolution TFT display costing £105 (ex. VAT). For all power consumption tests (see next page), we set this monitor's brightness to 50 per cent, at which level it consumed 15 watts.
