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 eggs

Pros: Plenty of room, a lot of fans, very pretty blue LEDs for the two front, and the one rear fan. awesome large top fan, runs slow, moves a lot of air! plenty of drive room, and relatively easy drive removal. I expect that this case will survive into many future builds.

Cons: absolutely nothing to complain about, you get exactly what you expect with the money you put down! :)

Other Thoughts: I would recommend this to anyone looking to future-proof his/her computer build!

5 out of 5 eggsI love this case

Pros: this is the best case for a basic build, i have 2 new ones and another i built with 4 years ago, if you only have 2-3 drives and only 1 or 2 video cards there is plenty of cable room. and this thing has lots of fans and fan expansion, the 2 new builds i did are so QUIET i hardly know they are running...and i love the blue lights!

Cons: i only wish it were a bit wider behind the motherboard tray to hide excess cabling, if i had a large raid going id go with a full tower of some sort

4 out of 5 eggsSolid but heavy

Pros: Solid, roomy, updated 3.0 USB ports, front load HDs

Cons: Very heavy

Other Thoughts: Bought it in 2007 and it's like solid armor, but for me it's too heavy compared to my other computer cases. Obviously, it's stood the test of time. Just beware if you load it up with various devices (which is the purpose of this large case) and clean it regularly, it's a monster to move to a work table. With the newest liquid cooling options, most builders don't need the large cavity for cooling that this case provides. Other than the weight, it's a great case.

4 out of 5 eggsUsed for about a decade

Pros: -Has lasted me through 4 rebuilds since I purchased for my first PC build
-Has good room for anyone building a basic PC or bang for the buck gaming rig
-Very good air flow for the money

Cons: -get's a little cramped and harder to run wires if you plan on filling your tower with 2 GPUs, 2 disc drives, and more than 1 hard drive
-will fit liquid cpu cooling unit but won't be as spacious as an atx full tower
-no way to get to the 200mm top fan area to clean very well
-only reason I'm replacing mine is because my newest PC build requires more room so I'm purchasing an atx full with a handle for easy transport for LAN parties

Other Thoughts: Like I said at the start, this tower has been going and working perfect for about a decade for me and has more than paid for itself over the years because I didn't need to replace it each time i rebuilt my PC. I would definitely recommend this tower to any gamer looking to save money where possible to free up more of their budget for better cpu/motherboard/gpu. However if you're building a more top end rig then you will want to go for a good atx full tower like I am doing now.

5 out of 5 eggsAntec Nine Hundred Black Steal ATX Mid Tower

Pros: Nice case. I picked this case because it has the most bays for my unRaid build. I used Icy Dock modules to install 8 x hot swappable bays. The front drive covering/hard drive mounting has thumb screws which made it ease to remove. The 3 speed fans are nice. The fans did not make a lot of noise at all. I still ended up picking up some Corsair Quite fans because of the color. The 200mm fan is really quite. In terms of air flow, the case airflow was awesome. It kept my 8 x WD red drives cool and i5 3.3 Ghz cool. I really like the stand off that are already for you to install your ATX form factor mother board. My Corsair MX750 fit just really good. I like the top storage holder. I can put thumb drives in or even a mug. Haha but do that at your own risk.

Cons: The clear side door should at less have a film to protect it from the hardware stuff box that bounce inside the case. I got some scuffs but not bad enough to care. It's part of how manufacturing package there product. Nothing to do with there case construction. The case does not have a fan vent cut out for a power supply to vent out but would be nice to have. There was one USB port on top of the case that was not punched out. There was no USB 2.0/3.0 mounting attached to it. It would be nice to that port be used along with the USB 3.0 ports.

Other Thoughts: none

5 out of 5 eggsMarvelous Case.

Pros: The case is a major step up compared to the inferior one i used to have. The fans are nice and quiet and allow plenty of air flow to keep all of your components nice and cool. The LED's are very vivid and really make it look like a real gamer case. I highly recommend this case to anyone browsing for a decent priced reliable desktop gaming case.

Cons: None.

5 out of 5 eggsGreat Case

Pros: it has good space for smaller builds, but it wont fit a large graphics card without moving some stuff around. it has amazing airflow and the built-in fans have 3 settings so you can adjust them if they're too loud. i also added 4 more fans just to optimize airflow. while the bays are kind of a pain they help with sturdiness and if you have to change something you don't have to take a lot of other stuff out to get to it.

Cons: the same problem as a lot of other: no dust filters. but for 12 bucks i got some that work great and weren't that hard to put in.

Other Thoughts: ive only had it for a few months and the only issue i have had is the dust. but once i got the filters and blow it out every so often like you should anyway, its not a major issue, just an inconvenience.
