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.

Amazing case 2/20/2017 10:26:25 AM

Pros: I have had this case 7 years now. Has never failed on me. The front panel is kinda jacked up due to plugging things in and my knee hitting the wires(which is my own fault). Plenty of space to upgrade. Power/reset works great. Best part the stock fans it comes with, still working to this day! Although, 1 is finally dying(only works on high), but they are not loud at all, IMO. Great air filter for the intake in front, which is removable and able to be clean easily. Swinging door on front makes ease for fan installation/maint. or changing hard drives. Wire management is good. Very smooth surfaces. Steel case makes it near impossible to cause static while working on it inside(your always grounding yourself touching it).

Cons: None that I have ran into.

Overall Review: I've only been using 2 fans these last 7 years. Using top 140mm as I take and back 120mm as exhaust. With heat sink and 2 fans on GPU it always ran cool and never had a heat issue. I'm actually filling all the fan spots with LED fans to give this case a "newer" look. And boy does it look amazing. 4 120mm blue and 1 140mm red. Perfect!

3 smokers in house, so I clean it every 3 months with an air compressor. Dust likes to hide is wire nooks on sides.

Wire management was very hectic at first. But once you learn how to use the nooks on the side, it becomes very easy.

Great case for a simple PC build 2/11/2016 10:50:18 AM

Pros: Small, sturdy, clean design and setup, plenty of room for some larger high-end graphics boards.

Cons: No real cable management is available in this case, so be prepared to get creative.

Overall Review: I have a gaming mobo with an old but reliable Radeon 6870 in this case. Everything has been running smoothly since 2011.

Best Case. (Period) 12/17/2015 10:49:37 AM

Pros: I've owned probably a dozen or so cases and worked on hundreds in my life and this is the best. It's modular, everything fits like it should, no sharp edges (you know what I'm talking about), it's not crazy large, has great air cooling, everything about it is easy and just works. I'd recommend to anyone

Cons: It's not crazy large. Lots of the new motherboards, video cards, power supplies, seems like everything is getting bigger and bigger. Except the solid state drives, they're shrinking. This case is not big enough to handle all the monster equipment but it does just find for my personal rig.

Overall Review: It's just about the perfect case. I didn't know unicorns existed until I found this one.

Fantastic Case 10/21/2015 1:49:33 AM

Pros: Spacious case, with numerous mounts for additional fans. Dust filters on the front of the case catch many of the bigger particles.

Cons: Price. There are many cheaper cases out there.

Overall Review: This is my go to case. I've built dozens of computers with this case. I've yet to find a case I like better.

Good case 9/17/2015 10:01:21 AM

Pros: Lots of room, easy to put in all the hard drives, etc. Very good customer service: easy to contact, easy to work with.

Cons: The front of the case is poorly made, which is why I took off an egg. The front USB ports have failed twice and had to be replaced under warranty. They also don't work for every device. For example, my external hard drive enclosure doesn't work with them, which is inconvenient. I have to get under the desk and plug it into the back.

Overall Review: I would consider another Antec case, but more research would have to be done to be sure that the front ports are well made. Perhaps that is why Antec discontinued this version of this model.

My favorite case 8/7/2015 8:53:27 AM

Pros: Fantastic air flow means quiet computing if you select quiet components. Easy to build, nice and roomy with good old-fashioned screw mounted drives.

Cons: Mounting 3.5" flash card readers requires and add-on kit. Mounting 2.5" drives required additional hardware (except for a single bottom mounted drive in newer cases). Sheet metal isn't as thick as the premium cases.

Overall Review: I build PCs for lots of friends and relatives. This has become my standard case. I've built up about a half a dozen of these without any issues. I prefer this case over the newer Three Hundred Two (which I've used a couple of times). My desktop PC is in a more expensive Sonata Solo and I'd prefer one of these.

Great case that's easy to work in 7/14/2015 11:18:47 PM

Pros: Finished edges, user-friendly design & control locations.

Cons: None.

Overall Review: This case has been a pleasure to own and use. It houses my always-on components, and is part of a build that is 4.5-5 years old now. The case is finished inside and has not cut me while I've had my hands inside. The front intake (with fan option) allows for a lot of airflow over heat-sensitive components. My next case will be, if not a sound-dampened Lian Li or Silverstone, another Antec.
