Assembly
Installing the motherboard into the larger chassis shows that there is loads of free space within the case, so you should have no issues at all with even an eATX motherboard. The chassis on top can easily fit a Mini-ITX board, but you will have to watch the CPU cooler's height as the PSU will sit right above it. The arrangement of motherboard-expansion slots and the fact that the chassis is very long allows you to also easily install full-length graphics cards.
Installing a 3.5" hard drive does not require any tools. Simply pick the plastic tray of your choice, slide it apart and put the drive into place before squeezing things together again.
Once filled, slide the drive back into the spot you chose. The spot for 2.5'' drives behind the motherboard tray is simple and functional, but requires the use of small screws and a screwdriver.
Installing the ODD is, once again, done without tools. Just pop out the cover, slide the drive into place, and flip the switch to secure it properly. While the lock does its job, it does not hold nearly as well as with traditional screws. It would then be a good idea to sink at least a single screw into the drive.
Installing a power supply is done by traditional means, with the use of included screws. That's it, guys and gals. There is nothing else to see here - keep on moving.
With everything installed into the larger chassis, the HAF Stacker offers a ton of room, so you will not have to worry about whether your configuration will fit within the confines of this case.
To show you another possible configuration, all hard-drive cages where moved into the top compartment for these last shots, which would leave you with all the space you would need to plant a large radiator into the front of the chassis, for example.
Finished Looks
With everything in place, the massive HAF Stacker chassis looks great. As you can see, I installed the optical drive into the drive bay at the very top, while the rest of the system rests inside the larger unit. A red LED lights up behind the power button as soon as you turn the entire system on.
The front does look a bit empty, as I could have stuffed a lot more hardware into the chassis. Previous owners of a HAF series case will note the lack of fans in the front and the missing red glow of the LEDs the cooling units usually come equipped with. Everything in the rear is where it should be, and I made a point of covering the openings in the top up with the parts CoolerMaster provides to that purpose. Last but not least, the large, tinted window gives you an idea of what makes the system tick. But you will not see much without interior lighting.
