Antec Black Steel ATX Mid Tower Computer Case

The team that brought you the Three Hundred is back with an enclosure designed to handle today and tomorrow's high-performance systems. Introducing the Three Hundred Two, the next standard in affordable gaming cases. Our newest chassis is built for gamers from the inside-out, from its aggressive front bezel, to its advanced cooling system. The Three Hundred Two is the rightful heir to the Gaming Series legacy.

Features


Antec

Cooling

To ensure that heat won't be a problem, the Three Hundred Two offers a rear 120mm TwoCool™ fan and a top 140mm TwoCool™ fan with four optional fans. It also features a side 120mm fan mount to cool graphics cards and another 120mm fan mount behind the motherboard try to help dissipate heat buildup. For maximum flexibility, top water cooling grommets are included for a custom water loop option and an enlarged CPU cutout.

Antec

Less Maintenance and More Gaming

Comes with total of nine tool-less 5.25" & 3.5" drive bays with two dedicated SSD mounts, a large cable management compartment, and two front panel USB 3.0 ports with an internal connector makes installation a 1-2 step. The Three Hundred Two also takes advantage of the cable routing holes behind the motherboard tray, making cable management a breeze. It can support a maximum graphics card length of 12.5" (318mm) and a removable, washable PSU air filter and front intake filter to top it off.

4 out of 5 eggsGood bare bones case

Pros: Good looking metal case. Very sturdy and lots of room inside. Items easy to get at and install. No flashy lights or gimmicks. Used to build NLE/Video Capture computer.

Cons: 2.5" drive bays do not leave a lot of room for wires to attach to devices, especially the one on the side. There is no adapter for 3.5" devices in the 5.25" drive bay. I needed to order an aftermarket adapter to get a multi-card reader to fit.

Other Thoughts: This case is an excellent value, however, be aware that there are only 2 cooling fans with the case so beware of cooling issues with some processors. Antec does not seem to make a 3.5" adapter for the 5.25" drive bays, so if you are installing a device that needs to accessed externally you'll need to get an aftermarket adapter.

5 out of 5 eggsSimply Excellent

Pros: - Lightweight
- Durable
- Nice textured black finish
- Very roomy

Cons: - None to speak of

Other Thoughts: First off, this is the first Antec product I've ever purchased, but after reading other reviews I decided to take a chance on this case. Long gone are my days of wanting a super-awesome windowed case with all kinds of visual niceties. The Three Hundred Two is very simple, but still aesthetically pleasing.

The construction of my case is top-notch in every respect, with enough space to fit far more drives than I'll ever need to. In addition, there are plenty of places to mount fans (you only get two, a rear exhaust and top exhaust, so plan ahead). I'm very happy with the interior space. Dare I say it has even more room than the huge Ultra Aluminus case that the Antec is replacing...

Overall this is an awesome product, don't hesistate to pick one up.

4 out of 5 eggsNice and Sleek

Pros: This is a wonderful case, I bough it to replace my Antec 300 with no USB 3.0
No ugly LED lights, no ugly colors, smooth and flat design in the front. I actually have one of these in my Entertainment center stand in my living room sideways, it blends in, and no one ever points it out or sees it. It hides very well. For the most part this case will not draw any attention. I find that PRO! As far as the air flow inside the case goes it seem fine, I am still searching for something better though.

Cons: Cleaning up a tower this size will take time and effort.

5 out of 5 eggsSeriously, an upgrade from the 300

Pros: The 300 was an amazing case. Simple, durable, and clean-looking. The 302 is an expansion of this with lessons learned. The 300 was 18" from top to bottom, 18" from bezel to rear, and 8" depth. The 302 is 18x19x8.5"... a minor increase of an inch in length and an extra half inch in depth.
The biggest thing this extra depth does is allow the hard drives to be mounted perpendicular from the motherboard and PCIe components. On the 300 I had an issue with videocards being hard to squeeze in, since the power cables of the video cards sometimes were at the very end of the card, exactly where the power cables of the hard disks would be. The rotation of the hard drives magically clears up miles of space inside so you can have some seriously huge graphics cards inside this case.
Along with mounting the hard drives sideways, there is now extra space for routing cables in the back of the motherboard tray area. It was quite easy to route my 5 hard drives power and data in such as way where you couldn't even see their spaghetti. The extra space back there is fantastic for taking care of things. The only wires that are strung around the case in a mess are short case fan power cords and the CPU power cable which was too short to route around the board.
The last very important fix from the 300 is the CPU cutout from the motherboard tray. This allowed me to mount my motherboard, and then mount the Noctua HSF I picked up to replace the Intel stock one. The 300 did not have a cutout... and it almost drove me insane trying to mount a Corsair water-system onto it on my last build.
More minor pros include the tool-less HDD system (which many cases have) and the tooless 5.25" bays. The 5.25" bay system is fairly secure, though it doesn't seem like it would be when you first look at it.
There are also two spots for mounting SSDs in the case, without a bay adapter. There are 4 holes where you can mount the SSD to the case in a fashion similar to a laptop mounting (not from the sides, but from the 'bottom' of the drive).
The two USB ports on the front bezel are replaced with USB 3.0, which remains largely untouched apart from the aesthetic curvature the front end has now. The front panel cords are plenty long to be routed using the cable management.

Cons: The cons are minor, but they're there. The primary is the lack of fans. You get 2 case fans installed, a 120mm on the back and a 140mm on top. They do their job, and they have 2-speed controls mounted on the back of the case, where the original 300 had the 3-speed controls just hanging inside the case.
The other minor con was that the PSU 'clip', that guides the PSU into place on the bottom was bent inwards on my case. I scratched up my PSU pretty bad until I realized I had to bend it back into a straighter shape. I was quite confused as to why it didn't fit initially.

The other issue is the filter/vent on the bottom. I tried to fit my PSU upside down, so the fan of the PSU was going straight out of the case, but my Corsair AX750's top fan I guess has the wire fan guard 'too tall'... preventing me from getting it to fit when I mounted it upside down. I could get it in there, but then the PSU was applying pressure to the filter on the bottom and I could not remove the filter. Maybe I don't get it, but I don't understand what they were going for there at all.

Other Thoughts: This is a budget case. It is available for cheap at several retailers and I forsee it going on sale a lot. While it doesn't have some of the filters and other trinkets of other sub-$100 cases out there, the very low cost of this one gives it a pass. Nothing on this case felt very cheap to me, so I don't think I'll have any issues keeping this for many years like my old 300.

If you owned a 300, and are looking at a new build, definitely buy this. I was originally going to use my old case for a new build, but after putting together this one, I'm so glad I got it. The biggest thing was the CPU backplate cutout... it made those secure-mounted heatsinks easy.

I did not get this at Newegg, so I did not have to worry about UPS shipping. It was packaged very well, however, and I can not imagine it having issues in transit, unless it was VERY abused on its way... in which case, maybe you would have an issue with the front bezel. The front bezel mounts in the same fashion as the original 300, and I've had several of those shipped to me without ever seeing one being broken.

Also, I'm not into traditional watercooling systems, and I can't imagine someone who's got that much invested wanting to spend sub-$100 on a case. But they felt it necessary to put those rubber-tube-pass-through-things on the top of the case, where I just think it looks silly.

5 out of 5 eggsGreat Desktop Chassis

Pros: I have a number of these for office computers

Cons: The fan on top is a bit annoying, as far as placement since users like to lay things on top of the towers.

Other Thoughts: Great little computer chassis for business

3 out of 5 eggsdamaged

Pros: These improvements to the Antec 300, such as, front panel USB 3.0 and tool less optical drive installation really stepped up the game for this mid tower computer case. Now if you could throw in a few blue led fans for the front we can make this the new Illusion case.

Cons: Shipping: the box was stabbed... looks like a small forklift whole that went into the case and bent the front grill at the bottom lower edge... I took 2 eggs off for the ding and please have antec send me a new front grill....I can't deliver the case to my customer with a ding on the front grill.

Other Thoughts: customer rebuild antec 300 case, amd quad core cpu, 16 gig of memory, powercolor radeon 6970, gigabyte 990fx ud3 motherboard,corsair 860watt power supply. Blue ray by LG. All parts from Newegg.

4 out of 5 eggsAwesome case

Pros: Lots of building room, many HDD bays, very nice cable management and it looks freakin' cool to boot. I especially love the tool-less design of the drive bays. Very clean.

Cons: Not really a con for me, but the case may be a bit bigger than the preview pics let on. Also the reset button is pretty small, but that may be on purpose so someone doesn't accidentally bump it maybe? What does irk me about this case though is the blue power LED is a bit intense, which sucks when you have your computer in your bedroom and you're trying to sleep while it's on standby. The spot for the power supply was also kind of tight. Putting my S12G in was a pain in the behind.

Other Thoughts: This is my first real case. Was building out of an old Compaq case before this one. If I had to compare the two... The Three Hundred Two is like packing the trunk of roomy SUV, while my old case was like trying to stuff a whole loaf of bread into a rusty soup can...

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

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.
