How to make your own home data center

["emoreno@xxxxxxxxx" <emoreno@xxxxxxxxx>]

I want to convert a storage room that is external to my house into a
home data center. This is a very small room (3foot X 3Foot X 10Foot)
and my idea is to have 2 or 3 computers + xbox + dvd players and other
toys; Some of them will be ON 24/7.

However, even though this is a very small room and small project, I
realize it requires some serious knowledge of data centers to come up
with a good design that will keep the room temperature and humidity in
acceptable ranges, keep the equipment working properly to prevent
damage and keep the costs and energy consumption to the lowest
possible.

Given my reduced knowledge about construction and data centers, I
think that I will need to pay someone to do the job for me.

Does anyone know of a company that could do this type of jobs?

Given the fact that this is just my home and the size of the project
is very small I hope this is affordable. Does anyone have any similar
experiences? Any information or comment will be highly appreciated.
