(Perhaps my idea of a data center is different to others, so as a brief explanation I am an IT consultant that deals with small to medium businesses from around 10 to 600 PC's.  This has allowed me to work in a number of small and large data centers and numerous small business server rooms.  Small business server rooms can range from downright crappy to quite elaborate, however all data centers I have worked in have at least visually looked quite similar with rows of server racks and the above mentioned fit outs.)
