Well I think I've found one. The Procurve 2510 Series:http://www.procurve.com/products/switches/ProCurve_Switch_2510_Series/overview.htm
It's a fanless, stackable, managed switch, And it's actually cheaper than the 1800 series.
Don't quite understand the difference between it being managed and the 1800 series being web-managed. Does this mean, for instance, that the 2510 series will be more difficult to manage?
