Back in 2001, the ATCS series made big waves and Cooler Master was known for uncompromsing quality and innovation with the entire series. Nowadays with the changed economic structure and crowded case market, the ATCS 840 does still hold true to those values. While we no longer see some crazy and "out of this world" innovation in the chassis, Cooler Master has taken all the good, functional and working features and slapped them into the ATCS 840, along with a few smaller additions. One of the most noteworthy and certainly most elaborate new additions is the pop-up top I/O. I am rarely surprised by features in a case these days, especially after reviewing so many over the years, but this one feature made me smile and shake my head in approval unintenionally.
The case also comes with plenty of cooling, having three 230 mm fans and a single 120 mm one, right out of the box. You even have the option to place three more fans or go for an internal water cooling setup with the included accessories. Some areas do feel much like misguided tries to add new and exclusive features. The black box in the rear - what is up with that? or the simple exterior access to the screws, securing the expansion cards along with lose front drive bay covers. That said, I still think this is a good case and the ATCS 840 still delivers on all its promises, but does not quite make you feel as elite as the ATC series did in the past.
