Pros: It's DEEP. It's menacing looking, sort of Darth Vaderish. There are lots of holes in it, and some unexplanable rubber flappy thingies on the bottom.
There is enough room inside for my 1993 Nissan 300zx twin-turbine intercooler. Honest.

Cons: Lots of wasted space inside.
The footprint is unusual.
Only one included case fan.
Limited uses for a generic system build.

Other Thoughts: I bought it. Duh. Note to the specs more carefully.

Being a design engineer, and having built maybe 100 systems over the years, thought I had seen it all. This case design is a new one on me.


Please look at the dimensions carefully BEFORE purchasing. Don't do what I did, and just look at the pics and trust the brand name. This is a really odd shaped, odd sized case, with quirky thermodynamics.

It appears to be for water cooled systems that require lots of square area to mount heat exchangers and large case fans.

If you are building in a crazy hot climate, or if your equipment runs red hot, and especially large, this case may work for you. There is lots of room, and the case is basically 100% perforated.

If you are a mere mortal system builder, like me, get something more practical.

I don't do RMA's, so this case is destined to become a gnarly Halloween mask, or a tomato planter.

Manufacturer Response:

Hello Bill,

I am sorry that teh case wasn't what was needed to really fit your needs. You can e-mail me, and or call 1-888-624-5099 ext. 169 if you have any suggestions on how to improve similar cases that may be built in the furture.

5 out of 5 eggsHAF Stacker 915F

Pros: Great product. Solidly built case with plenty of room and a great look. Easy to take apart and get to all the important components. Great instruction manual for those who need it.

Cons: None that I can note. The case worked exactly as I expected and had more than enough features for what I was using it for.

Other Thoughts: I picked this case because I was using it to build a new point of sale computer to run the back office for a small grocery store. The case has more than enough room for the motheboard, cpu cooler, power supply and fans. I love that you can stack 2 or more cases together. Not only does it save on space but it made it very easy for cable management.

5 out of 5 eggsLovin this Mini-ITX case

Pros: I got this case as part of a package deal (the full case and another mini-itx case) I like how this case has the front ports like how the full tower versions do. My only problem is now I have 3 cases and I'm still figuring out what I'm going to use them all for.

Cons: Maybe its because I got a package deal (3 cases) but I only got 1 bag of screws and that was packaged in the full tower I bought. I feel like I might be headed down to the hardware store to try and fix this problem down the road.

I guess I somehow expected this case to be smaller and use it as a media computer in my living room. Like store it somewhere by my TV but the size of it doesn't really fit in those square boxie book shelf things that are all the rage in living rooms these days. It's really my own fault tho, I suppose I'll just have to think of another use for this case :)

4 out of 5 eggsVery practical

Pros: The fact that they can stack makes it wonderful for a render farm I am setting up, I could stack 3 of these at least with no issues at all.
They are also very easy to remove all panels for easy access, and they go very well with other HAF products

Cons: I think they are way too deep, and there isn't really a reason why, I could EASILY add another tower rack of 4 of 5 HDD in the center of the case with no problems what so ever, making this case an amazing NAS server, but for that, you have to mod it yourself

Other Thoughts: Well, I would PAY for have a coolermaster little HDD rack to use in this case, pretty much like the one that has the R version of this case, and please finally ditch the optical drive bay

5 out of 5 eggsI Like it!

Pros: Roomy in the middle. Panels on both sides fit and slide nicely. Quick mount drive hardware (rubber shocks with a bolt in the middle which directly attach to a drive) are pretty slick. Lots of room for air movement, rear fan seems quiet to me.

Cons: The distance from the front-mount PSU to the mobo required an extension for the PSU I had (something left over from a random Dell desktop). The specs seemed to indicate that there were 3 drive bays AND 1 optical that could convert to a drive bay. NOT SO! there are 2 drive mounts and 1 optical that can convert. The optical slot is tall enough though to cram 2 3.5" drives in it. So I have 4 3.5" drives (no optical) and the 2 in front are pretty cozy, so they might get hot.

4 out of 5 eggsWorth it

Pros: Solid-solid, no warp or noise. Tight reliable fit on all parts.

Cons: room for only a couple drives, whether they be SSD or other. So if I wanted to run a 4 way raid with SSD I'd have to TAPE two of em down.

Mainboard mounting stand-offs had wrong female thread size - was more like the old small screws for floppy and CD drive. If you're gonna use stand-offs, get em from an old case.

Other Thoughts: Certainly a long case. Everything fit in easily, lots of cable tie points and very very little fiddling.

If you're installing a water cooler kit for the CPU its gonna be TIIIIIGHT. !! Will NOT mount the H90 and H110 size (140mm) sinks anywhere. I went with a Khuler - is very quiet.

5 out of 5 eggsIf Only It Was an Inch Wider....

Pros: Stackable is great for those of us with a space crunch. Solid case, easy to work with. Good ventilation. Easily portable, lots of room for water cooling or drives.

Cons: I realize this case was designed for mini ITX. But it's very frustrating to have such a great stackable case and be restricted to the limitations of mini ITX. Cooler Master design team, if you used a less boxy design you could flare out the base of each side about half an inch adjacent to the motherboard mounts and turn this into a mini ITX / micro ATX case, and greatly expand the market for it. It's so close....
