In Win Mana 137 Mid Tower Case Review

In Win is a company known for its unique style of cases, but today we’ll be looking at a rather non-stylish case by the company. It offers two USB 3.0 ports and even supports up to two SSD’s, in addition to the six 3.5” drive bays. Keeping this case simple helps keep bring down the price of the case, but will this drop in style equal a drop in overall quality? Read on further to find out.
