It is almost a requirement for any new case to feature tempered glass of some sort, usually in the case of a side panel. The tempered glass trend has been around for a while now, and some manufacturers are taking a look at some of their previous designs and incorporating glass side panels where they deem it to be appropriate. Corsair is not one to slack behind, and they have just released the SPEC-04 Tempered Glass, a slightly re-designed version of their popular Carbide Series SPEC-04 budget case that now includes a tempered glass side panel, for just $69.
