Antec’s Nine Hundred case was acclaimed for its combination of style and cooling design. The Twelve Hundred is an evolutionary improvement that capitalizes on the original design and adds even more for a design that can take whatever you throw into it. Even the largest 10.5” graphic cards like AMD’s Radeon HD 3870 x2 and Nvidia’s 9800 GX2 fit into any of the 7 expansion slots within its cavernous interior without limiting hard drive placement within any of the 12 bays. Mini ITX, Micro ATX or standard ATX motherboards likewise fit with ease.

A pair of three-speed 120mm blue LED fans exhaust heat out the rear of the case while a 200mm fan does so through the top. The speed of the fans, can be controlled from the outside of the case. Space and mounting points are provided for two more 120mm fans – one in the middle to cool the CPU or graphic card, and another bringing air in through the side panel to cool the expansion cards. Knockouts for liquid cooling systems are built in as is a platform for a reservoir or pump.

Because excess heat will kill any system, the case is designed to maximize cooling. The perforated front bezel offers maximum air intake by the trio of 120mm blue LED fans that pull air through the washable air filter. The front panel is finished off with top-mounted I/O ports for easily connecting an eSATA and a pair of USB 2.0 devices along with HD audio inputs and outputs.

  • newegg Increased Expansion With a total of 12 drive bays, you can expand your system to the limit
  • newegg Excellent Cooling The Antect Twelve Hundred comes equip with massive cooling options. A special 200mm fan on top, two rear 120mm fans , 3 front 120mm fans, 1 open slot for a side case fan, and one open slot for a middle fan give you ultimate cooling where you need it most.
  • newegg Cleanable Air Filters The cleanable air filters reduce dust build up on your expensive parts.

4 out of 5 eggs

Pros: Great quality on the build and finish, I really like the looks of it. I have had this case for over 3 years and the fans are still going strong with daily use.

I would have given it five stars if it wasn't for the filters being hard to access (See Cons).

Cons: Filters: I wish they would have made it easier to access the filters for cleaning. Having to remove both side panels and loosening the tray screws to slide them forward to get the front filters is a pain.

Mounting HDD: Now if you are like me and have had the case for a fair amount of time make sure you keep track of where you put the long screws that come with it for mounting HDD's (I keep a small storage case with all my extra stuff for future so this wasn't an issue). I wish some more designing would have gone into this so nothing special would have been needed.

Other Thoughts: Since I live in a very dusty area I finally gave up on the filters and removed them totally from the case and make sure I keep up on my cleaning of my systems, I find it makes it much faster to clean the fans/system and so on without them in place.

5 out of 5 eggsAwesome Case

Pros: Best case I have ever purchased. Mine has been running 24/7 for the past 2 years and I have yet to encounter a problem with it. All components can fit comfortably and there is plenty of room to upgrade in the future. This case is really durable and you can feel it in the weight. This is the only case I will ever consider buying in the future for more rigs. Fan placement is excellent and moves air very well to keep temperatures low.

Cons: None!

Other Thoughts: Antec is a great company known for their durability, reliability and longevity. I would expect nothing less than this stellar product. This one is a winner.

5 out of 5 eggsBest Case I Ever Bought!

Pros: Got this case back in 2/2009 and it's by far the best computer case I've ever bought! The case is big and roomy (you could hide a dead body in this thing) and it can fit even the largest video cards.

The fans in this case really move air and none of them have crapped out yet after 4++ years of near continuous usage. The only time the computer ever overheats is because the fan filters are clogged!

The fan filters do an amazing job keeping 90% of the dust out of the case and cleaning them takes about 10 minutes of your time.

This case is well constructed and made out of thick steel. It will very likely outlive me.

Cons: Fans are loud. The cost of the case doubled since when I bought it.

5 out of 5 eggsGreat overall case

Pros: Large case can handle any hardware you toss in it - Lots of space for cable management - Aesthetically pleasing - Great airflow - Fan/LED controllers give you lots of customization - Antec quality is superb

Cons: Dust tends to build up quite a bit even with cleaning out the air vents - Can't remove the front bays without taking the side panel off (at least I couldn't figure it out) - Foam covering front unused panels isn't secured

Other Thoughts: The cons aren't enough to drop an egg. The case is very high quality and I would use it again.

5 out of 5 eggsAmazing case!

Pros: Plenty of cooling
HUGE amount of space.
Front drive bays can be moved around 3 drives at a time.
Comes with all the fans you need. All adjustable without even having to open the case or rig it to software, although you CAN rig it to software if you want.
Very tough, very good build quality.
Supports watercooling and even has a location set aside to mount the hardware.
Good cable management.
A very clean look to it, it's lit up with the three fans in front, two in back and one on top (provided!) but it's subdued and not cheesey, it just looks amazing for those who want a little "wow" factor yet a clean look.

Cons: Please be aware that there are newer revisions to this case. V3 being the best. I got this one for 94 bucks on a black friday sale, but it's a little pricey normally for the newest revision. (around 150-250 depending on time)
This revision does NOT have
SSD mounting support, you'll have to buy it from Antec.
The filters on this older revision are harder to get to, you need to open the case and then unscrew 24 thumbscrews to slide the drive trays forward an inch in order to remove the filters for cleaning. The new revision has it setup so you don't need to do that. Just FYI.
Will fit pretty much anything you want, however it will not fit a Corsair H100 Liquid Cooler without offsetting the fans slightly on the rad. There are a few threads in the popular overclocking forums confirming this.(Yes there is a review website for the H100 that used this case, but I could never get them to give me a clear answer and it does seem like they had to off-set it somehow that's not clear in the pictures).
It will fit just about anything else though.

Other Thoughts: See it on sale? Buy it. It's performance and value are amazing.
Don't see it on sale? Wait for it or get something else.

5 out of 5 eggsGreat Case

Pros: Great case, amazing airflow, can fit pretty much anything in here and have room to even work around those tight spaces. Great case for gamers who need high powered video cards, and since those video cards are huge it was the perfect choice.

Cons: Kinda annoying to remove the front fans to clean them but the newer version of this case has that problem fixed.

Other Thoughts: When i bought this case a month later the newer version came out, I still love this case was worth the money and looks awesome. One problem though for my current situation is that i have pets in my house and they tend to shed their fur everywhere. Since the case has so many fans, i not only use it to cool down my pc but also to filter out my air lol. Usually after 2 weeks my dust busters in the front are all clogged. But i do not blame this at antec, this case is just great =)
