4 out of 5 eggsInexpensive, Love the Cable Management

Pros: Inexpensive; USB 3.0 front panel inputs; spacious for a mid-tower; neat cable management; CPU back access for water cooling plate.

Cons: Not enough motherboard screws included - only 8 included and 9 required for ATX board, come on Antec!
Only 2 case fans.

Other Thoughts: Knocked off a egg because I had to scrounge around to find one more motherboard screw. Otherwise, I like the case, especially the cable management feature which keeps my build clean and neat. 2 case fans included seems inadequate if they call this a gaming case.

5 out of 5 eggsAntec 302 Great case

Pros: Made a little wider than the Antec 300 for better cable management

Cons: Comes without the front bay fans that the 300 came with as standard

Other Thoughts: A great case for any size m/b

5 out of 5 eggsgood case

Pros: big case work lots of room
two quiet fans included
"toolless" install mostly
looks pretty freakin cool
front usb 3
area for cable management.

Cons: power button is missing a piece?

Other Thoughts: I like everything about the case so far. the "complaint" is that no matter how far I push in the power button the pc won't turn on. I have to open the side and remove the front panel and push the switch to turn it on. not a huge problem as the system rarely gets turned off, but it's still an inconvenience.

4 out of 5 eggsLarge Case, Begs For Lotsa HDDs

Pros: I maintain dozens of these among users, all max-filled with HDDs and this case gives those the most spacious spacing between drives, allowing the best air-flow from the front-mounted fans.

Substantial construction.

Cons: Substantial construction also means "heavy" and "large", which can be a negative for lugging around.

The case's drive-bays don't allow drives to be flipped for inserting - you can only install HDDs 'cables-in / nose out' which means to work on HDDs, you must pull the case out and remove both panels. The case is spacious enough for this, but the designer didn't see fit to use this wonderful consideration. I take points off for that lack of imagination OR lack of usefuless experience. Move 10 of these cases in a day JUST to access both panels, and it becomes an obvious drawback, compared to a certain Fractal case.

Other Thoughts: This is a Top 3 Case for users that need a lot of hard-drives - Fractal Arc Midi R2 allows drives to be inserted 'in' or out making a much easier drive-SATA-Cable maint routine. The CoolerMaster N400 has the old-style drive-cage but it has such substantial spacing that drive-maint is an ease. But this Antec 302 has the best between-drive air-spacing.

5 out of 5 eggssmall(er) case good options

Pros: This is the second of two Antec Three Hundred Two Black Steel ATX mid tower computer cases I have picked up over the last two months.

This computer case was easy to setup, good cable management for the price, cut out on tray for back access to CPU for folks installing oversize CPU coolers. The snap in / screw less mounting of the rails seems to work fine.

Cons: What was missing was the instruction guide. This did cause some issues dealing with the secondary support bracket for the motherboard PCI cards. Once I figured out I had to remove that plate to install the video card the rest of the build was easy.

Other Thoughts: I was not able to flip the case fans around to change the flow of air due to binding issues. Once I re-installed the fans back to factory default location they worked as designed. There could be a bit more room by offsetting the internal hard drive rails to allow a bit more room to fit power / SATA cables that have stiffer connectors.

5 out of 5 eggsBest case I've had in a long time.

Pros: Lovely black case.
Wire housing to improve air flow.
Many fan in/outputs with the option of water cooling.
USB 3.0.

Cons: Adding more fans may increase the noise you get from it.
The metal used to make the case feels a bit on the cheap end.

Other Thoughts: This case by far is the best case iv'e had in a long time, the one i upgraded from looked great, but had very poor air flow and it cause things to be slightly on the toasty side, which I didn't like. If your on a budget but need more more airflow in your computer i would say get it.

Still waiting to see how it fairs in 90 F or higher weather this coming Summer will update, if i can.

5 out of 5 eggssweet

Pros: Decently priced case, tons of room for cabling!

Cons: I ordered this thinking i was gonna get a Antec Three Hundred size case. This new model is significantly wider.

the SSD mounting on the bottom of the case is in a weird spot and you will have to force your sata cables into an almost 90* bend configuration. if you have low quality sata cables this could be a problem.

4 out of 5 eggs

Pros: This is a big case with plenty of room. The side panels came off easily and slid back into place without using a lot of force or having to spend a lot of time lining them up. The two included case fans are a nice touch and they have external controls. This was my first case with tool-less drive mounting, so I was pleasantly surprised by how quickly I could mount all my drives in place. The USB ports are located at the very top of the case, which is a subtle, but nice touch. My previous case had them about midway down, which basically meant the USB cables needed some extra length.

Cons: My earliest annoyance was that it didn't come with a manual. It's not a huge deal, but I had to pull it up on my smart phone and as I worked on this case. If you're familiar with this case, or others like it, then this is a non-issue, but this was my first build with it, so it would have been nice to have a paper copy included.

I was kind of hoping this thing was going to have a 100% metal exterior, but the front bezel is actually plastic. It's still high quality and durable feeling, but plastic nonetheless. This might have been a design decision to make it easier to snap the bezel in and out without tools.

The case has two additional holes on the top near the back, presumably to run additional wires from the outside to the inside. I'm not using them, so I just have some half-open holes in my computer. It would have been nice if the case included some plugs to close those up if you didn't plan on using them.

The power supply mounting was easy, but I felt like it could have used an additional metal brace to hold it upright.

The included case fans are a little louder than what I would have wanted. That said, it is easy to turn them off when I'm not doing things that generate a lot of heat.

Other Thoughts: Previous to this case, I never spent a lot of money in a high quality case. It never made a lot of sense to spend an extra 20-30 bucks on something that wasn't going to give me better performance directly.

For my latest build, I decided to actually invest in a good solid case. I was not disappointed with the Three Hundred Two. As I was moving components from an older case into this one, I couldn't believe how much more room was in this thing. Almost all the wires can run behind the motherboard, so you can have nice cable management if you're concerned with airflow (or you're just a perfectionist).

5 out of 5 eggsGreat Case!

Pros: Aesthetically pleasing, fans included, USB 3.0, 2.5" mounts

Cons: Build in fan controllers are on the back of the case

Other Thoughts: A lot of cases on the market have a "gamer" look. If you want something simple that doesn't look cheap, look no further!
