Review on 📦 Enhanced Cooling Box: EverCool Dual 5.25 inch Drive Bay to Triple 3.5 inch HDD Solution by Dave Moody

This article was exactly what I was looking for. It fits very snugly in two empty 5.25 bays and allows you to install 3-4 hard drives instead. Excellent quality fasteners, made of metal, not plastic. The filter for the fan is also of high quality. Also included is a mount for solid state drives. My only criticism of this product is the poor quality fan that came with it. This wasn't a big problem as it could easily be replaced with a matching fan (I replaced it with Silent Wings 2 - Case Fan - 80mm which I also recommend). All in all, if you're looking to convert two 5.25" bays into 3.5" hard drive bays, this is a great way to do it.
