A panic buy at Maplin produced a 250W ATX unit at =A318.98 (WF87U) - 'white-box', and not even described as low-noise, but it does have a variable speed fan, and seems quiet enough. The Iyo has been running for two hours without any obvious problems. However, the 5V rail is measuring 5.15V! One benefit of the unit - it does have a power outlet for ancillaries, but it doesn't have a switch. I may stick with this, or I might try for a more 'upmarket' device. --=20 Peter Bell - peter@xxxxxxxxxxxxxxxxx --- To alter your preferences or leave the group, visit //www.freelists.org/list/iyonix-support Other info via //www.freelists.org/webpage/iyonix-support
