Not every case fits every person's needs, Cooler Master recognized that and set out to make a case that people can adjust to what they need. Say for example that you want to pack your PC full of water cooling gear or an absolute ton of hard drives. The HAF Stacker can handle that and nearly anything else you might want to do. For CES this year a case modder even turned multiple stackers into a life sized monster. Today I?m going to take a look at the HAF Stacker 935 and 915F, the 935 comes with two models giving us a total of three pieces to try out different options.
