In the early days of rackmounted computers, the selection of ready built servers was quite limited and many of our customers needed custom designed and built servers to meet their requirements. These days, the selection of rackmounted servers is quite broad and the demand for customized designs has decreased. However, for those of you who need to convert a desktop computer to a rack mounted computer, or need a case to assemble your rack mount project or still want to custom build your server, CCSI here offers a number of rack server cases. We have Appliance Server and Storage Server Chassis, as well as general purpose 1U, 2U, 3U, and 4U cases. In addition to the chassis, CCSI also offers a wide selection of power supplies for these builds.
