Antec 900 Ultimate Gaming Cases

Antec Nine Hundred

The Most Versatile Gaming Case Ever!
Ultimate gamer case? You bet! With a partially perforated package that still finds room for four huge yet quiet fans, you have a seriously cool gaming case, and that's no joke. You can expect the Antec 900 to be ready for lift off, especially with the 200mm TriCool exhaust fan and perforated port atop this stylish case. Even mount a 120mm fan on the side panel! Contrary to some expectations, this case is extremely quiet, unless you have all the fans going at their highest settings, at which point you might hear...something.

The 5.25" bays will hold optical drives, burners, or even (gasp!) your aging floppy drive, and up to six 3.5" drives can be installed in cages behind the fans, arranged along the front any way you like. This case provides a plethora of possibilities, with room to explore new configurations of all the pieces. The PSU, in a departure, is at the bottom of the case, for better stability and thermal environment for the CPU.

The side window on the case, in addition to letting you show things off, provides additional ventilation, either by way of the vented screen or by the fourth fan in the box mounted into plastic for a clear and elegant installation. This is a sturdy case built of steel, with enough cooling technology to keep things frosty in the hottest action. Take one home today and build yourself the "coolest" rig around!

5 out of 5 eggsGreat Case for the price.

Pros: Great airflow through the case. Feels quality built. Came packaged nicely. So far I'm very happy.

Cons: None so far.

Other Thoughts: May have to do a little rearranging of front panels to fit longer graphics cards in.

5 out of 5 eggsAbsolutely Fantastic Case

Pros: -Had the case for 7+ years and only had one fan die on me about 6 months ago.
-Crazy amounts of airflow, keeps the inside of the PC nice and cool
-Blue LEDs look very nice especially in a dark room
-Absolutely love that the viewing window isn't simply a big square.

Cons: -Due to all the airflow had a tendency to build up dust (especially in hard drive bays), is real easy to clean tho
-The mic ports on the front give a static sound on the other end (friends in TS and Mumble always complained when I didn't use a USB mic)
-Cable management isn't the best but with some TLC you can easily make it work

Other Thoughts: Am currently building a new PC with a red/black theme. IF I could buy this case again but with Red LEDs there would be a very high chance that I would.

5 out of 5 eggsSO MANY FANS

-But seriously, the fans, there are too many for my motherboard to handle!
-Thumb screws are a nice touch
-LED's are also nice
-The window makes the inside of any system look gorgeous
-USB 3.0 is a really nice thing to have and especially on the top of the case, it makes it easy to access all that speed.
-Heavy and sturdy! It's highly unlikely that anybody's going to walk off with this behemoth!

Cons: -Could've added in some better cable management and possibly painted the inside of the case. Nothing to take an egg off for IMHO though.
-Heavy, so it's a bit of a pain to move around haha.

Other Thoughts: The pane in the side of the case scratches/scuffs quite easily, so that's something to watch out for, but it seems to be that way with all the computer cases that feature windows on them. Great case overall.

4 out of 5 eggsFans are all starting to rattle after 4 years

Pros: amazing airflow
metal but light
plenty of upgrade room (cable space is an issue though)

Cons: not enough room for modern high end GPUs (without case modification)
no cable management space
no easy access to the top 200mm fan requires case surgery to get to

Other Thoughts: I bought this case back in 2012 and it is pretty and well built. the fan I have been running on low since I bought it and my fans are starting to rattle. one front fan and the 200mm fan. I'm sure the front fan should be no issue to replace, but as far as I can tell they built the top 200mm fan into the top of the case and riveted the top on so without actually taking the entire top frame and cover of my case off I can not see anyway to access this fan. (if there is a way to access it I would love to know)

1 out of 5 eggsManufacturing Defect

Pros: New system build. No pros yet ... but will update.

Cons: First Issue so far ... Bottom bracket of back plane under where power supply is installed arrived bowed. New egg Customer Service suggested I install the power supply and see if there were any issues. Really. I test installed the power supply, which put excess pressure on the sideplane tab (part of the case) above the power supply and below the MB, which to me looks to stress the the sideplane that the MB is attached to. Over time, I am thinking that this could lead to MB issues.

I have opened a ticket with Antec and am waiting for a response.

5 out of 5 eggsAntec 900

Pros: I've had this case for 7+ years, no dead fans and all my parts are working fine because of the inherent cooling in the case. Two 120mm intakes in front, one 120 and one 200mm exhaust in the back and on top. It's the best design for airflow across the graphics card and motherboard.

Cons: No included fan on side, but you only need it if you're running a high end graphics card. Size, it's a big heavy case, but still a normal full atx factor. Cable management isn't easy.

Other Thoughts: I have the original version without the minor updates, but it's still fantastic.

4 out of 5 eggsGood Product

Pros: Pros:
- Solid and strong case, meaning your computer case will not set on fire like a plastic case.
- nice layout
- manufacturer gives you so many extra screws and items for this case

Cons: cons
- not enough space
- fans are quick to fail
- terrible to clean fans for dust, terrible to clean out dust especially when the fans conch out so fast.

Other Thoughts: I would recommend you buy this product but do so at your own peril. Buy extra fans, It took mine 2 years to fail.

I really enjoy the quality of the metal but I would like antec to integrate the new plastic hard drive clips and to make an easy design to remove and clean the fans in the front of the case. i paid 150 dollars for this case 7 years ago but I would have paid an extra 100 if they designed it better.

below is an excellent product of antec that incoporates my ideas however the case is plastic and is prone to being set on fire. I wish the company made the case below steel with the link below design.

5 out of 5 eggsExcellent case

Pros: The case looks great with the blue LED's on the front of the fans. Nice way to show off a new PC build.
There was plenty of rooms and options to move and configure the case to exactly how I needed.

Cons: Fans are 3 pin controls. Not a big deal if you know it up front, but I had a little trouble finding that but did know before I purchased.

4 out of 5 eggsLike it enough to use it again.

Pros: This is a nice-looking functional case; haven't had any major issues with it after nearly a year. The multiple fans are not too noisy, and keep the temperature down nicely on all but the hottest days (and they do get pretty hot around here--I don't blame the case for the few times I had heat issues this past summer.)

The tray on top is handy (I use it to stow an external HD) and the blue LED's are quite lovely.

ETA: I am still happy enough with this case three years later that I've decided to use it for my new build. The updated USB 3 ports on the front panel are a nice touch. Should have noted in my original review that the side panels are very easy to remove and replace.

Cons: Cable management can be an issue, especially if you have many drives or other devices that require bays. Rat's nests easily form between the MB, PCI cards, and power supply at the back and the bays in front, making working with the cables difficult.

On the other hand, there are enough bays that unless your PC is really loaded for bear, a little careful planning and arranging will give you empty bay space where cables can be tucked and not impact your airflow too much.

Minor annoyance: the small, apparently purely decorative cutouts on the top at the front collect dust. So does the tray and the angled front panel with the USB, audio and firewire ports.

ETA: The last one was built for me by a friend, so I've never taken the whole thing apart to customize it before. In doing so, I can understand why someone who builds many computers might not care for it. Nothing is tool-less, and there are a lot of screws. But if you're just building one PC once in a while and possess a screwdriver and a bit of patience, it's still perfectly serviceable.

Video cards have gotten larger over the years, and a large one or a dual setup may require some creativity to work around. The drive cages tend to get in the way, but they can, if necessary, be moved, or even removed while still keeping the attached front fans.

I would probably not recommend this case for a water-cooled rig, especially if you've got the aforementioned large or multiple GPUs, though I'm sure it could be done.

Other Thoughts: I don't think I'd recommend this case if you intend to stuff it to capacity with multiple drives, dual graphics cards and the like. I've got one PCI Express card (my GPU,) three hard drives and a BD combo, and I'd hesitate to put any other cabled components in without removing one of them. But for a simpler setup, it's fine.

A modular power supply is an absolute must.

A note on dust: I noticed a fair amount of it had accumulated on the case's perforated front grates in just a few days, though not too much was evident inside, so I built custom dust filters for the front panels (I used several layers of fiberglass window screen; it works well.) Not sure what the interior would look like at this point if I hadn't. The front of the case is recessed, which makes it pretty easy to fit them in place. I also purchased a simple Rosewill dust screen for the side panel cutout, and find that quite satisfactory too.

I covered the ports on the front panel that I don't use with black electrical tape to keep the dust out, and it blends almost invisibly with the case finish. Since I open the case fairly often, I'm using the same stuff to hold the side panel in place rather than messing with screws all the time; it fits snugly enough in place that I don't worry it'll fall off.

ETA: Haven't fired my new build up yet, but it appears that the rear fan on the current 900 is no longer LED lit. NBD, I moved it to the back of one of the drive cages and replaced it with an LED Rosewill model.
