3 out of 5 eggsBig

Pros: Big, lot's of room.

Cons: haven't even used it cause the screws holding in the Power Supply Mount are stripped so it's kinda hard to put in one when you can't take that mount off.

5 out of 5 eggsGreat Product

Pros: Very spacious and versatile with a generous amount of options for high air flow. Had this tower for over 2 years and to this day after having routinely conducting a full computer clean every 6 months, inside and out, it remains undamaged due to it's smart distribution of materiality between the metal and plastic. With it's pre-designed structure it holds 5 air cooling fans, but because there was so much extra room I had a spare 230 mm fan which I installed on the inside sandwiching the hard drive bays between two intake fans which is completely unnecessary, but it doesn't interfere with anything else inside.

Cons: The only con I found after 2 years is when it comes to fully cleaning the system. I like to dust out all the filters within the openings of the case which are covered by a perforated sheet of metal. In order to detach them you have to unfold these sharp edges of the metal which can be a pain figuratively and literally at times. Minor problem though, you can just use a tool or gloves if it's that bad.

Other Thoughts: When it comes to pros/cons the pros definitely outweigh the cons with the con really being such a little issue. The longevity of it's place in the market and the high volume of impressive scores are self explanatory. For those with enough room to accommodate it's large size and interest in having enough room to fit hardware of all sizes, then this was and still is a great product.

3 out of 5 eggsUseful case but it has its flaws

Pros: Its HUGE. The front/back space is enormous and you don't really even have to tie anything down in the back to be able to close the back panel. Comes with 3 200mm fans and the ability to have a big side-case-fan which is very useful if you're going to have aftermarket cooler cards in sli, giving those cards adequate airflow or exhaust. It is very spacious (except for one part which I'll get to in the cons) and has a lot of cool features. This case's forte is cooling gpus. It was made for the fermi cards (gtx 400-500 series) which ran incredibly hot, and the sidefan was meant to blow air onto the pcb pipes of the gpu. Its not really needed for blower-type cards anymore but is still very useful for acx sli cards as I've said before.

Cons: Even though the case is huge, the top compartment for whatever reason, is not. There's a few rails on the top which make putting in a radiator and fan AND routing the cpu power around the back almost impossible. You can still route it around the front but that kind of defeats the purpose of cable management. Also, its VERY hard to get wires up and around the top since there's only 1 very small opening to do so. Would've been a perfect case if the top compartment had some bigger openings with rubber grommets and the radiator mounting rails were higher up. There's also a lack of rubber grommet openings on the bottom beneath the motherboard, but that's probably just due to the case having the abillity to house extended ATX boards, which is just a trade off you have to live with.

Also the backplate openeing on the case is too small to put brackets behind the motherboard while its in the case, but not really a big deal.

3 out of 5 eggsNot worth the price - Far better options

Pros: Very Very roomy
Usb 3.0 on Front Panel
200mm fans
looks great!
some good coolermaster engineering (wire routing grommets, sliding power/led button shield, easy to use hdd and 5 1/4" drive bays)
Large window w/ 200mm fan
great packaging

Cons: I do have many problems with this case. There is a psu cover to hide your cords, which may be removable, but is extremely hard to place on again and route wires through when the build is finished.
my usb 3.0 front header came 1. way too short to reach my mobo in a clean looking way, and 2. filled with plastic shavings! which bent my mobo's pins to the point of it barely plugging in even after i fixed it all, and it does not hold in place easily, if you even somewhat touch it, it will fall out.
On my right side panel, not only are both panels extremely loud and hard to get on, the places of which the screws go into are drilled in the wrong places, it came with the top screw jammed between the panel and the main frame, and after i got both screws out it wasnt actually even on, it just fell off.

Other Thoughts: I am looking at it right now with my build finished, it looks great, and i feel that it will serve very well, even though it caused many problems during the build process.
Actually, it looks like the cooler master logo isn't even straight...
I thought that the build quality on a $180+ case would be far better..

3 out of 5 eggsBeware no way to get parts

Pros: Solid and big. Looks cool.

Cons: I've had this for a while now and long enough to change my system a bit. To my surprise there is no way to get parts off the US website. I had to order from Norway to get a new HDD tray and an SSD tray (it only comes with one). I also wanted a face plate for sd card reader. Bottom line check their website if you plan on needing any extra parts more than likely they don't sell them anymore.

4 out of 5 eggsCool Mastere HAF X Hight tower case

Pros: Impressive looking. Has 6 front 5 1/4 slots

Cons: No real instruction manual. USB 3 Port broke - blue plastic pulled out with USB stick.
I am unable to find a way to order a new part under warrantee or pay.
Web page won't take the serial number on the case and stops me from progressing.

Other Thoughts: Web page could be greatly improved as could the instruction manual for a $200.00 case.

5 out of 5 eggsSo much room!

Pros: Amazing space! Quiet fans. The easy-click drives are fantastic.

Cons: Need to buy extra sata ports for all this adaptability. And yes, fully loaded, this beast is heavy.

Other Thoughts: LOVE this case - it was everything I needed for adaptability for maintaining current build and updating. Only problem - came with a broken wheel and no idea how to get just that piece.

5 out of 5 eggsReally good case

Pros: Has 6 external 5.25" bays which I use for externally accessible HDD bays. The case itself actually has 2 of these by default in the bottom 2 slots which can be removed.
Plenty of room for CPU coolers.
9 expansion slots
Good build quality

Cons: Could have a little more space behind the motherboard for cables.

Had to take off the side fan's duct because the cables from my RAID card were in the way. Shouldn't be a problem for normal setups.
