5 out of 5 eggsA case for Serious PC Enthusiast

Pros: This case is the ultimate case for anyone that has a lot of components they need to fit for one PC. I needed two power supplies and room for a closed loop cooler, and this case has plenty of room to fit everything.

The cutouts from the top piece to the main piece are very big allowing for good cable management.

Cons: I had a problem with the top piece locking in place after it was assembled. When I went to move the case into it's final position after building the PC it came loose.

Other Thoughts: This case is huge. I knew that, and it is no problem for me because I am not storing it under a desk. But you should make sure there are no hight limitations when you want to keep this beast.

5 out of 5 eggsfantasitc case

Pros: ---amazingly well built
---tons of space
---love the stacking options for future cooling solutions and hdd arrays.
---tempered plexi window looks fantastic.

Cons: ---didnt include molex extenders to go from top stack down to bot mounted psu.
--- in top piece you have to use a slim mounted fan on the side closest to the front or the hdd tray clips will be in the fan shroud. (i simply removed the hdd clips.)
---needs fan cutouts on bot same as on top for increased airflow.
--- cant install top fan closest to front if you want to use your top 5.25 drive bay.
--- cant install rear top fan if you are using a dual 120/140mm closed loop cpu cooler in the top due to inability to run tubes elsewere.

Other Thoughts: mobo: asus sabertooth 990fx military spec
GPU: r9 290x (reference cooler)
CPU: amd FX 8320 (4.8ghz)
ssd: ocz vertex 3 120g
hdd: wd black 500g
psu: ocz fatality 750
ram: gskill 8g 1600mhz
corsair h100 closed loop cpu cooler.
(9) corsair 120mm performance fans
(2) 120mm delta highflow fans
(1) 92mm coolermaster fan
dual 80mm ram cooler.


-----with this i am able to maintain a cpu at 30 c under load and a my gpu with the reference cooler is able to run bf4 max settings for hours on end and not break 80 c <--(which is fantastic if you know about the r9 reference cards.


HIGHLY recommend this case IS fantastic

5 out of 5 eggsPerfect

Pros: This case is a mid + a mini with lots of customization options. All of my wires can be safe and securly hidden on the right hand side of the panle and distributed evenly. Its easy to take a part and even easyer to put back together. Currently there are 2 360mm rads hanging off the sides so it does look like a beast right now. Extreamly watercooling friendly!

Cons: Powder coating in the screw threads made it hard to get the stand offs in the main case. Get some good pliers and some gloves there are 9 after all.

Other Thoughts: I wish there had been more tie down spotsbut if you pay attention you can still keep wires in check. Also if you reverse the hdd's it makes it far easyer to run the sata and power cables in a clean maner.

5 out of 5 eggsSturdy, well built, modular case.

Pros: -Lots of space to expand and add your own personal touch.
-Support for 2 360 triple 120 RADs in the 915. Support for a 240mm double 120 RAD in the front of the case and an additional single 140mm RAD in the back.
-Good for water cooled systems especially with the 915 expansion.
-Very affordable and very sturdy.
-Removable 3.25" drive bays.
-Tool-less design on the drive trays make for easy installation.
-Modular design allows you to change your system build with very little effort.

Cons: -Only two fans are included. One 92mm in the front of the 915 and a 140mm exhaust at the back of the 935 (Planned to install some aftermarket fans so not a big deal for me).
-The manual leaves a lot to be desired but still functions.
-Dust Filters on the side of the 915 are secured with screws making them a little more difficult to clean than is necessary.
-Front panel does not have a reset button.
-The thumb screws securing the side panels were incredibly tight when I received the case.

4 out of 5 eggsI like the cases!

Pros: This case is pretty sweet lookin! I've not bought a full tower before and was a little surprised at the actual size but I really should have know better. All in all this is a pretty good case.

Cons: The only con I will add is that the case comes with a bag of screws for mounting whatever you need but I feel like there isn't really enough here, and some of the holes on the top and bottom of the case (ment to be stacked) would seem like they should have an optional covering.

Another thing I don't really like about the case is if you notice the smaller case that would attach to the big one doesn't have any front ports for plugging stuff into it. I plan on using this smaller case as its own separate computer but it's annoying that I won't have front ports for it.

5 out of 5 eggsMy dream case

Pros: Tons of space
9 HDD/SSD bays
4 ODD bays
Supports up to 3 360mm radiators, 1 240mm radiator, and 1 120mm radiators.
Sturdy and extremely heavy
It's beautiful from front to back

Cons: No support for side case fan, not enough to deduct an egg.
You have to remove the ODD and HDD bays to mount radiators on the 915.

2 out of 5 eggsGreat case but....

Pros: Great case and functionality

Cons: If you need to order a Replacement OEM I/O module with USB ports 2.0 and 3.0 or an extra module, they do not offer one on http://www.cmstore-usa.com (Cooler Master OEM parts website) that has both 3.0 and 2.0 . Even though the website shouse the connector for 2.0 it dose not come with it if you order a replacement or extra I/O module. This is a huge disappointment for me for the fact the smaller case I do not have or need 3.0 on that computer.( http://www.cmstore-usa.com/haf-stacker-915-i-o-module/?src=prn#ProductTabs )

Other Thoughts: Why would you sell an I/O module that is not identical to the replacement for the case?

2 out of 5 eggsGood Tower

Pros: Looks like it has a ton of possibilities for configuring, just plan on doing it all custom.

Cons: -Did not come with front fan.
-***Could not fit a 1200watt power supply.*** (there is -a bump that blocks the bottom power supply mounting)
-Cannot put an fans/cooler on the side pane.
-Placing watercooled cpu cooler requires alot of modification to the unit and cooler and or case.
-Go with the 935 unless you plan on customizing/cutting/do it youself cooling/mount a big power supply anywheres but the bottom.
-Definatly not a purpose built case has maybe too many options built in that an simple one is not possible

Other Thoughts: Bought this with intentionns of having two PC's in one. Opened the box and started fitting parts and peices and was about to take out the drill and cutting wheel just to fit my power supply (1200w). Then started to test fit my cpu cooler (radiator 2 fans) when i noticed that it would not be able to fit the top seciton unless i routed it to the add on where i planned on putting the mini motherboard and needed longer hoses and more customization. Looked online and found the 935 will fit my needs better. Might find a use for this case sometime down the road. there are some creative builds online but all custom, not what im looking to do just yet.

Manufacturer Response:

Hello,

It sounds like the case didn't meet your needs for what you were trying to accomplish. If you would like, you can send me an e-mail at eric_belger@coolermaster.com and or call me at 1-888-624-5099 ext169 and discuss any suggestions you may have so that I may pass the information you have to offer to our product management team.

Sincerely,

Eric

5 out of 5 eggsGreat Case with plenty of expandability

Pros: This thing is huge. I don't think its physically possible to run out of room in this case. plenty of drive storage, great cable management, and the ability to house two (or even three) systems. right now I have the 915R on the bottom housing my HDDs and DVD drive. very sturdily built, too. the tinted acrylic panel is a nice addition, if a bit of a fingerprint magnet. watercooling potential is huge.

Cons: a few nitpicks. the standoffs were a bit stubborn to get into place, and the included Phillips head adapter is completely useless (maybe I just got a junk one). a few of the drive bay caddys had the screws that hold the hard drives in place pop out, so they could be designed a bit better. also, USB3 to USB2 adapters really should be standard on cases with USB 3 ports. also, this thing is a behemoth, in case I didn't get that through. its about 3 feet tall. also, the 915R is useless on its own because it doesn't come with any power buttons or ports, making the mini-ITX mounts next to useless.

Other Thoughts: If you plan on using this as a multiple system build, get the HAF Stacker 915F along with it. it's a bit better designed for Mini-ITX systems. for any other use, this is a great case.
