Antec combines size, quality, features and low price to deliver the ultimate gaming case. The smallest of Antec’s “Hundred” series designed for the Do-It-Yourself gamer, it is equipped to deal with the increased heat output of high-performance systems as well as providing a flexible design to best suit your needs. Its overall matt-black finish shows that you – and your system – mean business.

The front panel includes a pair of USB 2.0 inputs as well as jacks for a headphone and microphone. The front bezel is perforated for maximum air intake and it has a washable filter to reduce dust within the system. Inside, are a total of nine drive bays – six 3.5” internal HDD’s and a trio of 5.25” external drives. Seven expansion card slots let you load up on graphic and other options up to – and including – a full height ATX motherboard. A rear-mounted 120mm TriCool fan as well as a top-mounted 140mm TriCool fan – both with 3-speed switch control – draw air through the case.

In addition, there's space for an additional pair of 120mm fans behind the front bezel to cool the HDD’s as well as the option to mount a third 120mm fan on the side of the case to cool the GPU. If you’d rather put your money into what goes inside the case rather than the case itself, the Antec Three Hundred is for you.

Room for expansion The Antec Three hundred features 9 drive bays and 7 expansion slots which give you room to expand your system to it’s limits.
Increased Cooling The Three Hundred comes equip with 1 rear and 1 top fan, as well as 2 optional front fan slots and 1 optional side fan slot. Fitting case fans in all slots will increase airflow to your valuable parts.
Compact Size The unit has plenty of room for your parts in a small 18”x 18.3” x 8.1” case.

Keith 5/20/2013 12:32:58 PM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 4/5Bad screws Pros: I built a rig using this case since the price was right. its small form factor let me fit it in my rather large suit case. it has a decent cable management system, especially for its small size. the air flow is awesome; I am able to run at a stable 62C with an air cooled i7 o'cd to 4.2ghz. I also like the dust screen. they keep a lot of the dust out of the case. Cons: The front bezel broke when i was trying to just move it. i hadn't even put it it my case to fly yet. it is just aesthetic but it is still disappointing to have a crack in my new case. This is the real killer. the screws to hold the mother board in don't stay tight. i go in weekly to tighten them. I have gotten blue screens because the motherboard shifts and my cards don't contact the m/b right. Other Thoughts: Back to the dust screens... they need to be cleaned a lot. My room isn't dusty but these things find it. All you need to do is wash it in the sink. Did you find this review helpful? Thanks for the valuable feedback you provided!

Solid construction, no frills, excellent fans. Did you find this review helpful? Thanks for the valuable feedback you provided!
SHSPVR 5/17/2013 8:55:20 AM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5Love this case Pros: I love this case I have 2 other and I would recommend this case since antec has been in the case business for a long time making petty reliable products. Cons: None Did you find this review helpful? Thanks for the valuable feedback you provided!
brokepar 5/16/2013 8:20:21 AM Tech Level: 3/5 Ownership: 3/5 Verified Owner	Rating: 5/5So Far So Good Pros: Case is Simple and built well, pretty much as advertised. I would recommend this case since Antec has been in the case business for a long time making sturdy and reliable products. Cons: Only thing I wish is that the power supply be located at the top of the case, my power supply which I paid a ton for barely connects to the top of my mother board which creates a problem with routing cables. But that's just my problem. Other Thoughts: Plain, Simple and effective Did you find this review helpful? Thanks for the valuable feedback you provided!
Dnob 5/15/2013 10:59:14 AM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5Great Case Pros: Great Case, well built, plenty of room. Cons: Does not come with a 5.25 -> 3.5 drive bay adapter, not needed in most cases, but I needed for a mini SD card reader and had to order the adapter separate. Other Thoughts: Used this case many times for many builds, always been very good to me. Did you find this review helpful? Thanks for the valuable feedback you provided!
N/A 5/14/2013 9:03:42 AM Tech Level: 4/5 Ownership: 2/5	Rating: 4/5Good case, but small Pros: Well built with quality components, nice clean look, and quiet. Room for 3 extra fans. Cons: A little cramped for my taste. Other Thoughts: I built a basic gaming rig in this for a friend just last night. We chose this case because of the great reviews it had which it definitely deserves, but it did feel a little cramped. There aren't many options for cable management and if we started putting in hard drives and pcie cards, you may have issues with air flow. A good modular power supply is a necessity in my opinion to keep clutter to a minimum. 0 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
muj0 5/5/2013 3:57:05 AM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5Quiet! Pros: Extremely quiet case for as many fans as it has. Plenty of room to work with. (Utilized a Cooloermaster Hyper 212) Well constructed. Cons: none Other Thoughts: I've used Antec before, they've never let me down on their quality. Did you find this review helpful?

C 5/2/2013 11:37:22 AM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5Solid Pros: Cheap Very nice case No flashy lights Easy access side panels with thumb screws Raised motherboard mount makes hiding cables behind it simple. Spots for extra case fans Cons: Says its ssd compatible. By that it means there are holes on the bottom of the case to screw it down. That would be nice, but the ssd I got came with an L shaped sata cable that was the wrong way and wouldn't fit when it was attached to the bottom. Other Thoughts: Very solid cheap case. Well worth the money. Did you find this review helpful? Thanks for the valuable feedback you provided!
N/A 4/27/2013 12:19:03 PM Tech Level: 4/5 Ownership: 5/5 Verified Owner	Rating: 5/5Very good case Pros: Had the case now for 17 months. I have the two intake fans on the front, and the two fans on the top/back. Didnt clean out until 12 months...very very little dust. Dust guard does fantastic and little dust gets in elsewhere. Plenty of room for my needs (gaming). Easy to open and take apart. Highly recommended. Cons: None Did you find this review helpful? Thanks for the valuable feedback you provided!
Blue 4/25/2013 4:20:31 PM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5Great value Pros: Has a 2.5" spot at the bottom for SSD. Has very many bays to install all sorts of components. Did not find any sharp edges. Comes with lots of thumb screws which makes me very happy. Came with 2 fans, one at the top, and one at the rear. Spots for more fans. Looks clean. Feels solid. Cons: There's an angle bracket I needed to remove at the bottom of the case in order to put in a PSU. Drilled out the 4 pop rivets. Other Thoughts: I would definitely buy this case again.
