5 out of 5 eggs

Pros: It contains perks one would see in a much more expensive case.
I personally would love to have tons of these just for the ease at which you can switch motherboards out.
Multiple levels in the case give it a more compact footprint while streaming more air over the components that need it most.
Hard drive bays are hot swappable and in the front
Lots of space to route cables

Cons: Taller than I expected, but I could have done the measurements so no eggs off.
Badge on the front cant be taken off without gaping hole. I was going to replace it with a sick MSI badge.

Other Thoughts: Not small enough for the top of a desk but I use it in my living room and I just barely didnt have enough room for it in the entertainment center, so the glass shelf is now resting a few inches in the air with wood blocks on the case corners (to keep from blocking the top vent) This was because I didnt measure and I was barely wrong enough to have to work around it.

4 out of 5 eggsAMAZING Case!

Pros: 4 Removable Panels
USB 3.0 Ports in front
Fan mounts where it counts
Easily removable HDD Bays
Removable interior Drive Bays
Removable MoBo Tray
Plenty of notches for zipties - Easy Cable Management
Plenty of room for a GPU like mine (GTX 670)
Removable dust filter for PSU
Removable mount for PSU
Side Vents, Mesh grille in front
Carrying Handles
Enough height for a tall CPU Cooler (See Cons)

Cons: Mesh top, but with a tall CPU Cooler (made by CM) WILL NOT fit along side a top mounted 200mm Fan (also made by CM).

Super Bright (obnoxious when flashing) RED Power LED. First case I have ever seen with a LED that wasn't Green or Blue.

only 2 - 5.25" Bays

Front Mesh Collects Dust, not easy to clean.

Other Thoughts: LOVE THIS CASE, but it's too bad you can't use a CM Cooler (Hyper 212 Evo) with a CM Fan (200mm), one would have thought they would have thought of this and measured the case accordingly before finalizing the design.

I bought a new Top Panel (the one with the window instead of the mesh) since I couldn't use the 200mm fan anyway and the Mesh allowed for extra dust to produce in my case minus the help of the other fans.

It looks great when fully assembled and was very easy to assemble, Cable Management with a non-modular PSU was surprisingly easy.

4 out of 5 eggsSpacious, but no Rebate...

Pros: 1) Tons of Air flow for the cooling components.
2) Toolless Drive bay installation.
3) X-doc implementation.
4) Tons of fan placements, I'm an Air cool type of person so filling out all the fan slots is kinda an OCD type of thing. and I love all the fan mount spots.
5) The indented handles on the sides, great for lifting to LAN parties (if you have a lightweight system)!

Cons: 1) I purchased the EVO variant which means I swapped out the SSD bracket with a HDD. Now I could purchase a SSD drive sled from a third party vendor but I want the whole bracket to be swappable.
2) On my product (this won't be applicable to others) my MOBO tray sometimes won't cooperate when I want to reinstall the tray.
3) Rebates...I purchased this case along time ago but still have yet to receive a rebate in the mail (did the necessary paper work when doing so). and it's been 34 weeks, originally the rebate was set to 15 weeks if I recall.

Other Thoughts: Time for the nitpicks, 7 expansion slots for extra cards, I wish there could of been 8 but that what I spent my money on.

No dust filters with the side vents. dust filters for the drive bays are "frilled"

A great paper weight :P

This case is fantastic. Just I want my rebate.

5 out of 5 eggsGreat Case

Pros: - Cool Design
- Main Cpnstruction is very sturdy
- Great Heat Management; I am air cooling a AMD FX-9590 perfectly (Antec Heat Sink). The case comes with 2x 120mm fans in front; which is all I have in ATM.
- Filter Screens; Keep my dog's hair out of my case
- Plenty of room in main compartment

Cons: - I would not recommend the Hot Swap Bay; its made of plastic and feels rather flimsy. Also the Sata connector it plugs into screws into the back with no reinforcement. Lots of reviews of it coming undone. (there are two more internal bays though on the side)
- The entire front of the case snaps on and is made of an ABS Plastic. I didn't realize this when I purchased the case, but It still looks good
- PS area underneath MOBO and main compartment is tight. If you have a modular PS and want to add cable later on, You will need to remove your MOBO and essentialy dissaemble your build.

Other Thoughts: I purchased this case having known about the bad hot swap bays and the tight PS area. I still gave the case 5 stars. If you want a full ATX case that looks different with good heat managemet, you aren't going to do much better.

4 out of 5 eggsBest Cube Case

Pros: -Very sturdy
-Lots of air flow
-PSU filter
-Thin clear top mesh

Cons: -Cable management could be easier
-The way the hot swap bays work
-Motherboard try definitely not designed for ATX even though they do fit

Other Thoughts: This case is by far the king of cube cases. Its cable management could improve slightly, but with a fully modular PSU it shouldn't be a problem for most enthusiasts. So I recommend buying a full modular PSU with this case. They case has great airflow. Keeping all components between 30-40C even with the fans turned down to half RPM. Though it could have TOO much air flow. Some of what you might not notice on the pictures for this case is that it has a lot of holes on the bottom of the case. These help with cable management, but I feel they would allow a lot of unnecessary dust to enter the case. Here are my two major gripes with this case, and the only reason it didn't get a 5/5 egg. The hot swap for the hard drives on the front. If you want to take out the holder in the case that holds the drives to make room for more storage, you can. Although when you take it out it leaves nothing to support the hard drive trays which just happen to be part of the pieces on the front of the case. So unless you want a big hole in the front of your case you should probably just leave the holder in. My other problem is with the motherboard try. When you put in an ATX motherboard it covers the cable management hole used for the 8-pin cable connector on the top of the board. Other than these 2 things this case is pretty much my dream case. At least until companies invest more time in making cube cases.

5 out of 5 eggsGreat Case So Far

Pros: Everything fit very nicely, lots of cable tie downs. It was a little different for cable management with the two levels but it does allow lots of air flow over the mobo.

Cons: It is a little noisy being so open, but I still gave it 5 eggs because it is a HAF (High Air Flow) series and is kind of designed that way, plus my fans are low, low end.

Other Thoughts: Really nice case all around.

4 out of 5 eggsCooler Master HAF XB EVO

Pros: ~Cube case, unorthodox and easy to find a place to put it
~Horizontal Motherboard, No Card Droop/Flexing CPU sockets
~No frills Matte Black, looks great in any theme
~Great cable management potential, even for non-modular PSUs

Cons: ~Can hardly fit any tower coolers with the top 200mm fan ( 212 is 5mm too tall, two CM products dont work together :& )
~280mm Rad Liquid Coolers are unusable, even with 140mm fan mounts.
~Only one SSD adapter, two would have been great.
~X Dock works half and half, not super reliable

Other Thoughts: After moving on from a line of standard tower cases, I decided to mix it up and go for a cube case, this or a Corsair 540. This was on sale so I took the chance and it seems to pay off. Decent airflow, some good expansion options.
