Keep in mind that when a server is outdated and you own it, you can resell the parts. Most of the time companies that are providing a service who actually own the servers and colocate them in a facility have already worked out a cost structure where the server would pay for itself over a couple of months. The truth is owning is always better, your actually able to save alot of money going the owning route and yes it can be very profitable reselling the servers you own!
