In the future i will be using a PowerEdge Server of Dell, and because I don't want to have such a loud piece of hardware at home, i was looking
for a server-housing possibility. A lot of them ask how many power-consumption this server has, and guess what... there is nothing in the technical details about the consumption.
But i found the following great rack-planner. This tool is for planning how your 19'' rack will look like, what power heat will be produced and last but not least what power will be consumed. You choose a rack, choose a server, edit the server tell how much RAM HD, if it will be idle most time or most time used what processor etc....
Really nice tool, here is the link to the rackplanner.
