When it comes to a chassis for your computer, there are many that you can choose from, including small form factors, mid towers, and gigantic full tower cases. These cases are great, but what if you want to save space or have other needs, such as for a file server. Sometimes tower cases are not feasible for every project and this is where rack-mountable cases come into play. Almost everyone I know has some type of file or backup server, and most have multiple ones placed all around their rooms. With a rack-mounted solution, all the computers can be placed in one location, making it easier for managing and maintenance. Being a student, I have several servers that I run for my studies and have found that rack-mounted cases have served my needs tremendously, allowing me to place powerful hardware in an easily-managed case. However, there are some drawbacks to rack-mounted cases; inadequate cooling and, depending on the size of the case, the hardware that can be placed in it. Unlike tower cases, which come in SFF, mid tower and full tower dimensions, rack-mounted cases come in Units. The smallest unit is a 1U case, then there is 2U, 3U and the big daddy 4U, which is the equivalent of a full tower design. Today, we are going to be taking a look at a 3U case from In Win, the In Win IW-R300.
