Guys we've been using Compaq server from past 4-5 years and its working fine.We are having a small organization and our need is fullfiled by this server.
We use primarily Dell servers (several different models, based on the number of spindles needed and other requirements), but also have some white box servers typically housed in Supermicro enclosures.
We've been having a decade long debate on white box vs. branded servers, and over the years have gone back and forth, and I don't think there is a clear 'right or wrong' consensus yet.
Well, I am using ToodleDo. It is one of many browser-based tasks system. I believe ToodleDo goes fine beyond further web-based task systems because it is really further perfect to call ToodleDo a Tasks Server.
