Cooler Master may be a bit lacking in the HAF 935 department with provided airflow, but with the plethora of locations for more fans and possibly many radiators all inside of this concept gives the customer the ability to maximize the design to suit their own needs. Where this chassis hits the nail on the head is in the Stacker moniker naming. I have seen many a pedestal, and I have seen them for water cooling, or even phase change systems, but I cannot recall an instance where it could do those things as well as allowing for a system to be installed as it offers drive bays, and motherboard mounting on top of the basic design in a pedestal. I also like the ease in which Cooler Master has designed the slide rail systems that makes stacking these components dang near fool proof.
There are no issues with mounting anything inside of the 925 section of this design, everything there is well thought out and laid out in a way that makes every bit of wiring easy and with a short of a visible run as possible with the good placements of the wire management holes on the motherboard tray. I did install a motherboard and video card into the 915R to see about the expansion card slots, and even in the 915R, I found I had alignment issues just like I saw in the 915F. Also something to consider in this design, is that if you plan to stack the 915R with water cooling and radiators, you are going to have to remove the hard drive bays there, and they don't allow for 360mm radiators with fans to go on the side panels with it in place. With just a little bit of work, you could easily add four radiators into the HAF Stacker 935, and up to 12 total fan locations to fill to improve on the below average thermal results we got with just the limited air flow provided from Cooler Master.
Even back at the beginning, I think it was the simple but aggressive styling of the HAF series that always kept me liking them, and I even used a couple of them at great length with no issues to complain about in the long term either. If you were a fan like I was of the aesthetic appeal that has been the leading reason for HAF cases selling, you will not be disappointed with the appeal of the HAF Stacker 935 either, as it shows obvious heritage to older designs. If a normal super-tower isn't quite enough room, and you have quite a bit of height for a chassis that stands near 28 inches in height in the two piece configuration, if you want to stack three boxes tall, make room for a 37 inch tall chassis.
I strongly think that Cooler Master is onto something big here, and that is not just a play on the size of this chassis. While the HAF Stacker 935 and the 925F combination does take this chassis from huge to enormous, there is just so much customizable goodness and an ease to the build that makes the HAF Stacker 935 really hard to pass up, when you consider it will only set you back $169.99.
I, for one, am thinking like a mad scientist at the way I need to incorporate this chassis into my office, for some reason I feel I must find a full time use for a chassis of this caliber.
