Antec Three Hundred Black Steel ATX Mid Tower Computer Case

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 matte-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 3.5in. internal HDD’s and a trio of 5.25in. 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 three-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.

5 out of 5 eggsGood Case

Pros: Very quiet and very good air flow at a cheap price.

Cons: USB ports in the USB Module at the front of the case is just as delicate as you might think. Something to think about if you have kids that plug things in the front and leave them there, then dogs that go walking past.

5 out of 5 eggsAntec Three Hundred Black Steel ATX Mid Tower Computer Case

Pros: Enough space for my Cooler Master Hyper 212 EVO. Lots of drive bay space.

Cons: None so far....

Other Thoughts: Only had this for about a week and just finally ordered the last of the parts i need. The 120mm rear and 140mm top fan should move plenty of air as well.

5 out of 5 eggs

Pros: - Cheap
- Well built
- Nothing has broken for the 2 years I've owned this case and the two computers I've built with it
- Came with a lot of screws and motherboard standoffs
- Case fans are pretty quiet

Cons: - Very hard to manage cables inside this case
- Impossible to press the reset button so I didn't even connect it to the motherboard
- There are metal plates that were connected at the top of the 5.25" drive bay that vibrated and made a very loud noise until I twisted them out of the case

Other Thoughts: - I've never plugged the connectors for the leds on the front panel in so I don't know how well those work.
- When I first built a computer with this case I used a Corsair CX600 non modular psu. I regularly had a problem with my computer shutting off until my brother found that some unused connectors from the psu might have been shorting out on parts of the case. The computer still never worked after due to problems with the motherboard but that may be a problem for some people.

5 out of 5 eggsSubtle and Extensible

Pros: The best choice for enthusiasts who want a professional look.

Subtle styling and well-built. Filter is easily removed for cleaning. I was able to Crossfire two large graphics cards without a modular power supply (but it's tight). Buttons work well enough. Plenty of finger screws. Air flow is more than adequate.

Cons: I was unabled to hail passing UFO's by the strength of its standby LEDs.

Other Thoughts: You'll want a dust filter for the side fan if you use it as an intake.

5 out of 5 eggsSolid, silent.

Pros: Case is on, sitting by my leg. The fans are barely audible.

Cons: I don't like the "swing out" type of sides: they require extra room to get them detached, unlike sides that slide an inch back then pop out.

Other Thoughts: Came with a bag of two DOZEN extra thumb screws. Just in case your site is infested with thumb-screw gnomes.

5 out of 5 eggsGreat case!

Pros: Good cooling, I like the fans that came with it as well as the potential for 3 extra fans (120 mm)

Cons: The size of a graphics card is very limited. I ended up having to remove some rivets to take out the HDD bays ( i just got an adapted and put it where an extra CD drive would go, also very happy with this modification).

Other Thoughts: Great case. if you want a bigger graphics card and use a SSD (mounts on bottom) or just one HDD this case would be great.

5 out of 5 eggsvery impressed

Pros: very high quality, and it shows! Very good air flow. HDDs staying cool is top priority, but doesn't hinder cooling to the motherboard. edges are rounded off on the inside so you don't injure your hands while working on it. 120mm and 140mm fans are naturally quieter and include individual speed controllers that can be mounted nearby. All together VERY solid. Antec's own quality 3-year warranty is also solid. There is no cheesy lawyer-lingo or "limited" stamped anywhere. They just make good on their promises. I almost feel like throwing out the warranty anyway, because the packing materials are awesome! No damages in shipping are happening to this case! closed-cell foam all the way! they even protect the cable terminations with anti-corrosive packing! Also included are more than enough THUMB SCREWS to mount any and all hardware you can imagine. and they threw in some zip-ties for cable management as well.
I feel like they are actually thinking of their customers.
oh, and I just checked out the reset switch, it's recessed, and almost impossible to activate accidentally. right on!

Cons: I have to really try hard to think of something bad about the case... yea, I got nothing. the included external usb ports are NOT USB 3.0. But it would be the easiest thing to replace that.
.....
um... you have to remove the side panel
to release the front bezel and clean the air filter, but then that just means that things aren't going to be flopping open in transit to LAN parties etc.
that's about it...

Other Thoughts: honestly I just bought it because it was on sale pretty cheap. I had no idea it was this good, I'm delightfully surprised!

4 out of 5 eggsGreat case for the money

Pros: Cheap got this during black friday sales only 20$ after a mail in rebate other wise it was 40$.

Cons: All it is missing is a fan in the front to suck/blown air into the case the fans that come pre installed work great and on low speeds are very quiet.

Other Thoughts: plenty of options at 40$ cases but getting it for 20$ was a steal in my opinion

2 out of 5 eggsNot that great anymore

Pros: It's a case. It can hold your stuff.
Can add 2 front fans for better airflow.
3 pin fan headers with adjustable speeds.

Cons: Outdated. Budget case.
Cut corners on paint for the case.
3 pin header fans. No USB 3.0 header.
Cable management isn't great for non modular PSU.
