Cases are often a forgotten part of the computer but are important to the end-user besides just the looks. A Med Tower case will generally have more expansion than a mini-ATX case, as a Full Tower case will have the most expansion of the three. Silverstone cases are a favorite of this site as they have provided Motherboards.org with many samples and are easy to work with in general. They build cases, power supplies, and other computer components. I recently reviewed the Kublai Khan KL02 case and today the case on the review bench is the Kublai Khan KL03.
