5 out of 5 eggs

Pros: Very sturdy. Lots of options for cable management (comes with cable ties and lots of places to attach them to.) Removable motherboard tray is godsend when putting on a bulky aftermarket cpu cooler. PSU is mounted underneath the motherboard tray so keeping cables out of the way of airflow is trivial. Lots of fan/radiator configuration options.

Cons: Like some other reviewers have stated, the left panel (from the front perspective) is a little loose, but it's only noticeable when you're moving it around; it doesn't make noise during operation. I'll probably bend a few of the pins later to firm the grip.

Other Thoughts: Cooler Master, consider offering swappable power buttons if you're going to choose the LED color for us. Not that big of a deal, but would be a nice option to have.

4 out of 5 eggsAwesome airflow, and sturdy!

Pros: excellent airflow.
plenty of room inside for parts.
panels are sturdy as hell!

Cons: the hot swap dock isn't working.

Other Thoughts: when you're building in this case make sure you attach all of the cables you need into the PSU. I put my rig together and completely forgot to install my CD/DVD drive, had to cut all the zip ties and remove the motherboard tray so I could get the cables plugged in to the PSU.

about the hotswap dock. on my case. HHDs are getting power, I can hear them spinning when plugged in but they just don't show up. Don't know whats going on because when I plug them in to the regular sata ports they show up just fine.

that is the only reason I'm knocking an egg off. not really THAT big of a deal for me. I'll probably just remove the PCB and use the slots as regular mounting bays for my extra HDDs.

another that is annoying me, but isn't a con. the left side panel doesn't want to fit tightly like the other panels. doesn't rattle UNLESS you touch it. only bothers me if I bump against it while shuffling things on my desk.

other than that, this is an AWESOME case!!

5 out of 5 eggsIt's BIG!

Pros: Full size ATX MB "desk-top" type case with good airflow at a sub $100 price. Free shipping and a rebate also helped.

Cons: None

Other Thoughts: Its BIG! Measure carefully if you plan to install it on a shelf in your HTS.

5 out of 5 eggsAwesome case!

Pros: I bought this case to build my HTPC/Portable gaming computer. And its been great, amazing airflow. My stock intel fan has along with this has given me no heating issues. Extremely spacious, I only have a MicroATX motherboard in it atm so it looks very empty inside, but overall very nice!

Cons: none

5 out of 5 eggsOriginal XB owner now EVO owner!

Pros: 1. Awesome build quality all around. Nice and sturdy chassis that you only get with cold rolled steel, not sissy aluminum
2. Chassis paint job is a nice slick texture and tough, not easily scratched
3. Great cooling options all over, it is a HAF case after all
4. Great interior layout for installing equipment of all kinds
5. Awesome cable management options with all the built in wire tie downs. There is no excuse for shoddy wiring in this case
6. Side panels with built in handles make moving case around a total breeze and are very sturdy. Great for LAN parties!
7. Removable mobo tray is slick, easy and very useful!
8. Thumbscrews all around, thank you CM!
9. Case just looks awesome, a nice change from the years of tower cases.
10. Power and reset buttons are a nice, modern Smartphone style push/click style instead of the spring loaded buttons we've had for decades
11. Case just begs to be modded!
12. External PSU bracket makes PSU installation easy and allows for big sized PSU's with no issues. PSU fan filter also works well and is easily removable.
13. Then entire case is just so "solid" all over. No chassis flex whatsoever and the panels hardly bend even when you try. Again, steel cases FTW!
14. Water cooling setup people are gonna have a wet dream with this case!
15. You can fit a e-ATX mobo in this if want, just be sure to put electric tape on the board and or edge of the mobo tray to prevent shorting it out
16. All the internal cabling is black, so no eyesore rainbow cables too worry about.
17. Coolermaster has finally put in a good quality hot swab PCB with better cabling layout and SATA power instead of molex. No more PC noob building mistakes
18. Front intake fans have been upgraded in the EVO chassis, nice job CM!
19. All cases can be removed from lower chassis assembly in the EVO vs the old XB, kudos to CM for listening to customers!
20. The SSD only drive cage from original XB can now fit 3.5'' drives with EVO. Another kudos to CM!

Cons: 1. Tool less 5.25" bay adapters are STILL flimsy and basic. You can remove it and put screws in on one side. For a more secure optical drive, push in the right side tension tabs about 1/4'' and that will help a lot to keep drive from shifting around
2. For 140mm fans, you either need to install them inside the case or trim the front benzel for them to fit, the case instruction manual needs to be updated
3. 80mm rear fan mounts somewhat useless in my book but at least its an option for peeps who need lower level airflow
4. Removing front intake filter requires entire front benzel to be removed. Just wipe the front fan grill with a swifter duster or damp rag and be done with it.
5. Front USB ports are USB 3.0 ONLY with NO mobo adapter. Just an FYI, not an issue for me though.
6. Fully loaded, the case is heavy. Wussies need not apply
7. Its a big footprint for this case, make sure you have the room!
8.. This case is a HAF, so don't expect noise reduction of any kind with the panels on, plan your cooling setup accordingly.
9. Still no removable front intake dust filter makes baby Jezus cry...
10. It would be really nice to get a flat plate bracket adapter for the PSU for those who don't want our PSU sticking out of the year.
12. The gap between the case and PSU during installation is still too tight, making it easy to scratch your PSU.

Other Thoughts: I've been searching and waiting for years for just the right case to replace my beloved but aging Antec Mini P-180 case. When I first saw this case after doing some late night google searching for new and upcoming cases, I just had to have it. This is my first Cooler Master case i've bought in many years as i've been an Antec fan for over a decade. I am impressed with the design and layout of this case, CM really did a good job here.

I purchased the original HAF XB when it first came out in Nov of 2012. I did some mods to it and got to meet the designer of case at PAX Prime 2013 and the product manager of CM. He was impressed enough to offer an exchange for a new EVO case cause I was bummed out to hear about the changes the EVO had and was coming so soon and I hadn't my case for long. I forgot about the deal and asked him almost a year about it if he might still offer it and CM is shipping me a free XB EVO upgrade, I don't even need to send my old one back! Now that's ultimate customer service and satisfaction!

5 out of 5 eggsVery nice test bench

Pros: Pretty much everything I would ask for in a test bench.
Material choice and build quality are excellent.
I like its flexibility - removing the panels you get a open test bed, with panels on you get a traditional case. This comes in handy when you don't plan to work on the system for a while. Otherwise dust accumulates too quickly.

Cons: Not much.
Some further improvement on hot swap HDD holder would be nice. It's good design and easy to use, but does not seem to be very durable.

5 out of 5 eggsWonderful PC Case

Pros: Excellent case. I use it for a WHS 2011 setup. Adding HDDs is easy the interior is easy to get into to add or remove parts or replace stuff. Thinking of getting another one for my PC.

Cons: The one I have I can't put a 200 mm fan in the top panel. I have one and I tried it and it won't screw in, and no other size will work, but that's ok. It cools the board very well and I won't subtract an egg for that.

5 out of 5 eggsbest air flow cable routing case under 100buck

Pros: PSU bottom mounted with separate air filter >>check

two front mounted intake fans included>>check

MB mid horizontal mounted removable great for clean out of the airflow cable routing >>> check

included hardware to mount two 2.5inch SSD HD below MBscrewws, other mounting options no running to store to mount anything>>>check

two 3.5 quick release front accessable drv bays >>check

two additional 3.5 drv bays with screw less mounting>>check

optional one 200mm inside top exhaust fan with room to spare>>>check

optional 120 back of case mount for additional exhausting air >>>check

removable sides top and front for access to any component>>check

I have two of these , I did not buy them from new-egg I paid 90.00 in feb 2014 lv this case. will never go back to vertical cases.

Super easy to get access to anything. looks great with or without covers. If care is taken when setting up all cabling is easy to keep out of the way. great design HD and SSD cages are removable for a complete custom setup. I bought these to setup two identical systems for altcoin minning. with three gigabyte r9 290x oc's in each unit. with three of 1350w of gpu heat dispersed with everything in the case w/o water cooling. amazing.

Can recommend for builders gamers or mining. save your budget for components. does not look like a 90.00 case but for max cooling and customization look no farther. impress ur friends by the use ,not by flashing lights or stupid leds. j

Cons: none than stick out for design or long term use

5 out of 5 eggs2 year update...

Pros: After 2 years owning this case, I still love it. I never get tired of the reactions I get when people see it for the first time. I installed the Cooler Master V8 GTS in it and it works well in this case, but you will have to remove the top fan if you installed one. I modded the top panel by removing the factory mesh insert and replacing it with a piece of 0.118" polycarbonate. I was able to reuse the factory push pins that held the mesh in place so it looks factory installed.

Cons: Mine is the first model so it doesn't have 3 1/2" internal HDD mounts, just 1/2" internal and 3 1/2" hot swap. Not really a con as I only have two 1TB 3 1/2" HDDs, no SSD yet...

Other Thoughts: Cooler Master sells the windowed top panel on their store page for $13, but they want also want to charge you the same amount for shipping. You can get a 12" x 12" x .118" piece of acrylic at nearly any hardware or home improvement store for around $5, or a piece of polycarbonate the same size for under $10. Just trace the mesh panel and cut it (I used a skill saw with a finish blade), mark and drill the holes with a 1/8" drill bit and you have a factory looking windowed top panel in roughly 20 min. The plastic push pins work perfectly with the .118" panel. just discard the black plastic washers that were below the mesh.
