Pros: this case is Perfect for my needs, both sides come off, the top comes off and the front comes off leaving you with a bare skeleton ( Perfect for the Modder ), there is one removable 3 stack drive bay, once it is removed the inside is completely bare for you to do to as you see fit. Each side panel can hold a maximum 360mm radiator or 2 240mm radiators

Cons: absolutely NO cons,

Overall Review: I am still drooling over what I'm going to cut first, The window I'm going to cut into the left side panel, or the duel drive bay opening I'm going to cut and build in the front for a Dual bay Reservoir. I am using this with a Thermal take case, so you are not just limited to one brand of case, Measure- Measure-Measure and be ready to MOD.!!!!! to your needs

Pros: THE GOOD +1: Solid case. Cooler Master's uses metal and mesh to create a durable case that feels industrial and solid (will not get damaged during shipping, guaranteed). +1: Built to stack. It can be used in conjunction with the 935 and or 915R/F quite nicely; the top is removable and the bottom has cut access areas to reed cables and tubes through to other stacked cases. Plus the 915F/R cases are relatively cheap (especially with rebates and sales). +1: Convenient size. Its small form factor means it can be used for multiple purposes (gaming PC, home entertainment station, server, router) and way more portable than other towers. Total: +3 Eggs

Cons: THE BAD -1: Poor case design. The drive mount pillar obstructs two 120mm fan mounts and basically obstructs the third (unless you bend the door catches and mount all the way to one side of the screw slots for fan mounting) which also means that you cannot mount a 140mm fan either. The other door can only logistically have either a 120mm or a 140mm fan (assuming you have a video card), perhaps two 120mm or 140mm fans if you only had a PCI wifi card. I would love to put an intake fan near the motherboard but the case door won't allow for that due to not having door mounts extending that far and un obstructed by the dive mounting pillar. This drove me nuts and is probably worth more than just one egg deduction. -1: Expansion bays. Yes it has two and thus can support a full video card but the slots showing the inputs are manufactured slightly too small and may block video card ports. My MSI N650's mini-HDMI was blocked by a few millimeters, nothing an angle grinder and a steady hand couldn't fix; that's why I deducted it an egg. -(Slap On the Wrist): Poor marketing. It claims this case to be for cooling but the design counters that marketing point. Infact, the 915R* probably has a better chance of having more fans mounted given the design (drive mount beam). Ergo better cooling and more dedicated drive storage. Total: -2 Eggs

Overall Review: AND THE UGLY Note: Starting Value: 3 Eggs +0: One 120mm stock fan. Depending on what you are doing this could be a problem coupled with the poor case design if you want more fans. For that go for the 915R* for better fan luck. +0: Micro-ITX = 1 PCIE port (choose one: video card, PCI wi-fi, or another PCI adapter). Although an inconvenience, there are other ways to get wifi (ethernet port, USB wifi, or a wifi enabled motherboard). +0: Bad drive placements/mounts. Not saying that the rubber mounts are bad (actually they are great), rather the clearance of the drive from the case may be an issue depending on your power supply and its power SATA; if you have power SATAs in series, then it won't be able to connect to the mounted drives. The 915R* has a drive rack with enough clearance. For me it was a problem I overcome with a custom modification to give my drives enough clearance from the case. Not enough to warrant an egg deduction. +0: Cable management fun. It might be an issue given the case's form factor and your power supply. Word to the wise, zip ties. You can figure it out but it will take some time. Where is the fun in easy, right? +0: CPU clearance. Tons of vertical space; you can fit a Hyper 212 EVO but the horizontal space due to form factor is to be wary of because you can easily block either RAM slots or the PCIE slot. +0: USB 3.0 support recommended. Without USB 3.0 support on the motherboard, the front two USBs will be useless. This will require a more expensive motherboard especially given the form factor. *Side Note: If you decide to go for the 915R instead, just know that a water cooler is my suggestion due to the clearance above the motherboard on the account of the top rear mounted power supply. But even then you're bound to run into other issues like where to mount the grill and fan of the water cooler and fan placements given the video card length. So pick your poison.

Pros: The case is highly durable, stackable (duh, but it really works), and is easy to work in. Honestly I don't think there is anything better or worse about this than the 915F. It is a "pick your poison" kind of thing where you get neat and easy hard drive installation and access with this case, but at the cost of clearance over the motherboard due to the rear-mount psu. I have my improvement mods in the "other thoughts" section, which kept me from buying the 915F. Nice drive cage. Can take bigger radiators with some modding.

Cons: The rear mounted psu means you can't overclock (unless you have a liquid cooler or very good low-profile fan-sink. Even then, installation isn't fun when you know that upgrading means taking out the psu to get at the mobo. There is only a 92mm front fan. The psu is ONLY (and ONLY) supported by 4 screws. I have a fix for this though...

Overall Review: This is how I improved this case: 1) I painted two 2"x3" l-brackets from the hardware store black (heat resistant non-gloss coating) and installed them directly under the psu to give it support. This required some drilling, but the end-product was great, especially since the black-matte spray blends with the case. 2) I installed a 120mm fan between the hard-drive cage and mobo. This dramatically increased air-flow and improved my chipset temps. ------- Overall the case is wonderful. I have three identical server boxes (stacked) for different purposes. It is nice to have this system. As an IT technician it is great to have a home-friendly server rack! This case makes this a reality. In the future, I may remove the side panels to experiment with adding a single air-cooling system via large air-ducts - similar to enterprise server rooms.

Pros: I've built a number of machines and this case is small, seems to be cool. The only thing strange is the storage of the hard drives. I put in a 1TB HDD and a 256gb SSD. and they are attached with screws and rubber grommets. The picture was only slightly helpful. I do not plan on stacking this case, as the small form factor was what I was looking for.

Cons: Would like a cover for the bottom for some cable management if not stacking.

Overall Review: Installation was easy, both sides and the top come off.

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.

Pros: Low profile, but also very spacious for use with an ITX board along with a big video card and power supply. And I'm talking about a really huge power supply!!! Gorgeous case with excellent ventilation. I don't even need the included fan. I'll likely use this case for many years to come.

Cons: The old 1000w power supply I'm using uses an unusual NEMA 5-15P to IEC320 C19 power cord so I can't put the front bezel on. It's a very unusual power supply so most folks won't have this issue. Not a big deal to me anyhow.

Pros: Ever since I saw these babies on Newegg & Linus Tech Tips I've wanted one. Yeah, it's too big...big deal! I'm lucky, I don't have a wife to nag me that it's larger than her plants! To the naysayers: yeah, size does matter! I love the flexibility. I'm going to keep buying these monsters for future builds. I'm just beginning to explore the possibilities. This first HAF Stacker is going to run my brother's geothermal/solar/wind powered compound. And the mini-ITX in this case is going to house his I-5 ASUS gamer.

Cons: if I had a con I wouldn't have bought it...

Overall Review: Just because I really enjoy being redundant: IT'S BIG!!! (945) It won't fit under your desk, on your book shelf. If you live in one of those 600sf mini homes you'll need an addition to install this. If your hardware doesn't fit in a 945 CM HAF Stacker, consider building your own datacenter!

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

Overall Review: 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
