3 out of 5 eggsWorks but not without flaws

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: The power supply mounting is the best design I've seen by far. The removable dust filter and use of a spacer to keep the PSU off the base of the case is an excellent design. The HAF 912 doesn't have this feature and I had a piece of paper clog the vent and kill the PSU.

Cons: The xdock connector has two SATA ports - broke with little to no force. What broke away crumbled in my hand - had to remove the board and connect the hard drives directly. Not impressed with that design or use of materials.

Other Thoughts: Would like to see the option for large fans mounted on the left and right sides of the case to cool the top and bottom at the same time. May be interesting to see the PSU mounted vertically with the bottom fan directed toward the side of the case.

5 out of 5 eggsBest value case in the cube form factor?

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: -Very well constructed, feels sturdy and durable
-LOTS of air flow, lets components breathe
-Horizontal MOBO helps minimize stress on PCIe slots from heavy GPUs and CPU coolers
-Removable MOBO tray makes installing components in the bottom chamber relatively easy
-Fun to build in, looks SEXY when completed
-Built-in fans are surprisingly quiet

Cons: -The SATA power connector for the hot-swap bays is on a short cable that is stiff
-All of the unfiltered air flow allows dust and other airborne particles easy access to the internals

Other Thoughts: I purchased a custom filter kit from DEMCifilter that virtually eliminates the second con. I had my eye on this case for quite a while and was excited to use it for my build, WAS NOT DISAPPOINTED!

5 out of 5 eggsExactly what I was looking for

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: This was the only reasonably priced case with a horizontal layout. The other horizontal cases were more of test benches. With that said, this case is set up to be "semi-test-benchy" with things like hard drive hotswapping, but it's not annoying and everything feels firm. The case also comes with a bunch of extra parts, you can set it up for ATX and Micro-ATX, overall very pleased with the price, quality, and design.

Cons: Nothing really. I had a little bit of trouble mounting my hard drive to the tray, but that was an extra 3 minutes of work for a case that I plan on having for the next 5 years.

4 out of 5 eggsFantastic case with minor issues

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: Extreme positive air flow
Runs very cool
Looks amazing, especially with an LED top fan
Includes two 120mm fans.
Radiator mount in the front
Can fit more in your case than you think you can.
Super portable and light, easily transportable.
Sturdy despite being aluminum inside.
You can get a clear top panel if you want one.

Cons: Included motherboard tray standoffs did not fit the motherboard tray (your experience may vary).
Cable management may require some creative engineering.
USB cable may require some care to seat properly.
You will have to disassemble everything to get to your power supply and drives in your case.
Manual is pretty unhelpful.

Other Thoughts: If you're looking for an ultra-portable case that moves an insane amount of air, look no further. I use this as a gaming rig that I can pick up and move with me, and it works great. The internal design is a multi-tier setup: the power supply, drives, and cables go on the lower level, the motherboard sits flat on the top. The case is large enough to support even large graphics cards with a water cooling system, and you should even have space to run SLI. Be advised, however, that extreme cable management and creative installation of your devices will be a necessity here. You will want to use the included zip-ties to tie anything in the way down because space and airflow is at a premium here, and anything cables in the way may end up getting sucked into a fan and you'll have a terrifying chopping sound coming from your system. The motherboard tray is hit or miss. It comes with standoffs for your motherboard in the included screws, and you are going to want to install those, but mine were so wobbly in the tray that when I attempted to screw the motherboard to the standoffs, turning the screws just spun the standoffs! I eventually worked around this by installing standoffs from another motherboard tray which worked fine (except for one that I had to have someone clamp with a pair of needlenose pliers), but I shouldn't have had needed to do that -- a little disappointing for a name as big as Cooler Master but there you have it, and with some creative engineering I made it work regardless.

When completed, my case booted and ran instantaneously, though the USB front panel didn't work... so one disassemble and cable reseat later and it started working. I can't explain it, I really thought I seated it well the first time.

I recommend you get one of those Cooler Master Megaflow 240mm top fans and install it in the top. The one with the LEDs has this cool optical illusion effect where it looks like a cryogenic gas is spraying into your case.

Ultimately, an excellent case despite a few minor issues.

4 out of 5 eggsGreat design with a few overcomeable flaws

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: - Ample room for even the largest of graphics cards and CPU coolers. I have a GIGABYTE GeForce GTX 760, which is a massive card, and a Cooler Master V6 CPU cooler, which stands very tall. Both items fit within the case without issue. This is the first case I've owned that fits the V6 with room to spare.
- The two level design makes it fit nicely on top of a desk or table.
- Designed for quickly swapping out parts, so it makes a great test bench case. The top and sides come off quickly and easily.
- Two internal 3.5" bays, two external 3.5" SATA hotswap bays, two 5.25" bays.
- Two carry handles on either side make it very easy to pick up and carry this case.

Cons: - While the upper level is very roomy, and lower level gets cramped very quickly. Cable management is a must, especially in the lower half of the case. Full-size ATX power supplies fit, but it's a tight squeeze behind the hotswap bays.
- Only included two 120mm fans, both behind the front vent. I had to also order a 200mm fan for the top, a 120mm fan for the upper rear, and two 80mm fans for the lower rear. When ordering a 200mm fan for the top, make sure it has the correct mounts.
- There are no external 3.5" bays for things like 3.5" card readers. The doors on the hot swap bays are connected to the trays and won't close with things that have faceplates that are meant to be flush with the front of the case, so I had to drill new mount holes in my 3.5" card reader so it could be mounted on the tray and the door still closed.

Other Thoughts: Overall, I really like this case. I've had no issues with it I wasn't able to find a workaround for to suit my needs. The lack of cooling is easily overcome by ordering a few more fans, which cost me $30, and taking a fan out of my old case.

This case is very solid and surprising larger and heavier than it looks in the pictures.

4 out of 5 eggsLove the case only minor issues

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: - Lots of mesh/fan spots for high air flow

- love the 2 hot swap drive bays they work great

- love the tooless design, makes for easy access to inside(unless your using 200mm top fan)

- lots of space around mobo and underneath for wire management

- handles are nice

Cons: - my top 200mm fan didn't fit the holes, holes were rectangular my fan has a square mounting, ended up drilling holes in the mesh

- the power supply is a bit cramped into the hotswap drives back, it work ok and nothing is uncomfortably close but it makes things difficult.

Other Thoughts: i love the case overall!

3 out of 5 eggsGREAT case BUT it needs some improvements!

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: 1) Depending on your use the footprint can be a positive OR negative. In my case it provides a positive. 2) Compact design allows a substantial air flow across the motherboard and components in the top half (upper deck) of the case (see the cons concerning the lower deck below the motherboard).

Cons: With a compact case it should be expected space is limited, with that in mind... 1) You'll want to be sure to use a modular power supply with this case (one which allows you to use only cables that are necessary) if NOT then things are going to get crowed around the power supply. Look at pictures/video reviews of this case internally, especially those that are fully populated to get a better sense of the space requirements. Especially a build that does NOT use a modular power supply. 2) The clearance allowed internally behind the hard drive racks (both the removable hard drive bays and the internal 3.5" rack) is going to be extremely tight when all the cables (SATA/power) are connected. The rear of both racks have very little space between them and the power supply. The cables behind the internal 3.5" rack with standard 3.5" SATA hard drives snapped in will be "nearly" pinched. This can be managed BUT be careful or jacks and plugs are going to be damaged if things are not installed carefully and proper strain relief provided (there are zip tie mounts strategically positioned for strain relief). There is a PCB board on the back of the removable drive bays with some frail connections used for the SATA power plug that can be easily damaged if bent or twisted, zip ties are a MUST here. This should entail a better designed. 3) The removable hard drive racks can NOT be locked and are easily opened. This could be disastrous while the computer is on and operating, especially during active hard drive operations. Locks are a MUST for removable hard drive bays. 4) The bottom deck does not include the rear mounted 80mm fans (x2) and are highly suggested, especially if ALL the hard drive racks will be populated. I would even go as far as attaching via Super Velcro a 92mm fan along the side of the removable hard drive bays (where no fan mount is provided) to aid the cooling of those bays. This lack of available cooling is noted in some reviews as causing possible hard drive failures. Additional holes should have been provided in the sides of these bays to allow for greater air flow around installed hard drives (you can drill additional holes in lieu of this oversight). 5) The top grill of the case is advertised as allowing for the mounting of a 200mm fan and I purchased one to mount in the top grill. Well, LOOK VERY HARD at the pictures/videos of this grill and note the holes are NOT aligned as a PERFECT square and let me know if you are successful mounting a 200mm SQUARE fan without drilling new holes in the grill, I was NOT able to mount my 200mm fan. The fan holes in my grill measured exactly 180mm x 110mm (a rectangle) which you can notice when looking down on the top grill, no where close to a 200mm SQUARE mount. My request for help on this matter to Cooler Master has yet been unanswered...until today (March 14th) Cooler Master replied stating the 200mm fan is NOT a standard 200mm fan and REQUIRES the Cooler Master 200mm "MEGAFLOW" fan (did anyone read that anywhere in the specs or description)? So be WARNED, do NOT purchase a STANDARD 200mm fan for the top grill, look specifically for the MEGAFLOW fan.

Other Thoughts: Unless you are into case modding keep in mind this case is designed for simple use. Mount a motherboard with required components, an optical drive, and jam it full of TB hard drives (or SSDs) maybe using RAID and a quad video system. It can be a simple but powerful gaming rig. Using a 200mm "Megaflow" fan in the roof along with ALL other fan options in this case will provide a GREAT cooling environment, especially if using a Corsair liquid CPU cooler such as the H50/70 with a 120mm fan mounted in the rear top deck. It should be highly noted that adding even an inch to the depth and width would have been a major advantage internally without detracting from the external footprint. Additionally, if you have an optical drive mounted in one of the 5.25" bays and don't have any major plans for the remaining bay, take a look at this NewEgg item number (9SIA3913US3586) as a way to further expand your hard drive flexibility. Note this item provides additional external USB 3.0 ports which will require an additional internal 19 pin header to use (most new motherboards provide a single 19 pin USB 3.0 header for plugging in your front panel USB 3.0 ports). NewEgg lists two excellent PCI-E cards which can provide additional internal 19 pin USB 3.0 headers depending on whether your motherboard has the required headers, check out item numbers N82E16815256006 or N82E16815287019.

5 out of 5 eggs"Cool" is the best way to describe the HAF XB EVO. And it does.

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: The designer of this case has obviously put machines together and knows what is needed. The case feels sturdy and has almost all thumb screws throughout and snap in hard drive rails. There are cable tie points embedded in the metal in key places. Also, adequate extra hardware was supplied to include a socket for the motherboard standoff studs. The built in HD swap bays are a big plus.

Cons: At 16 x 17 inches, plus room needed for air flow, it definitely takes up some real estate.

Other Thoughts: I have had a lot of cases over the years but this is the most versatile and well designed yet. I would strongly recommend it to a friend.

4 out of 5 eggsI love the design

This review is from: Cooler Master HAF XB EVO - High Air Flow Test Bench and LAN Box Desktop Computer Case with ATX Motherboard Support

Pros: I love the cube design, instead of the traditional tower. Excellent airflow ventilation, especially with the 2 - 120mm fans in front and the 1 - 120mm and 2 - 80mm fans in the rear, i didn't have to add the 200mm up top, but going to add 1 just because I can, lol.

Cons: the only thing I have a complaint about is the space for the power supply (EVGA 1200W Modular) is a little tight even with the extension
