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 eggsGreat case

Pros: - Solid construction
- Big rubber feet
- Good air flow
- Two large fans (120 mm and 140 mm)
- Excellent cable routing
- Easy mounting of drives
- Lots of room internally

Cons: - The two USB connectors on the front panel are a tight fit, making it difficult to insert cables; but they do seem to be loosening up with use.

Other Thoughts: I bought this case for my very first DIY computer build. I was a little concerned when I started thinking about how to route all of the power and data connectors inside the box -- many of the comments left by buyers of other cases complained about this. However, this case makes it incredibly easy to route cables. In fact, it was actually fun. There is a separate compartment for passing the cables, so they don't clutter up the hardware compartment.

Internal drives don't require any screws or hardware to mount; the case includes snap-on rails that work really well. Also, Antec provides enough rails for ALL the drive bays, not just one or two. The drive bays are oriented so that they are perpendicular to the length of the case, making it really easy to get units in and out. Plus, the bays are designed so that drives can be installed facing left or right, giving you a lot of flexibility for dealing with the cables.

The included fans are quite large and create a lot of air flow. Both fans have a little switch on the back of the case for hi/low speed. I keep them both on low. Even on low they are far from silent, but seem pretty quiet for their size, and I'm easily disturbed by noise. There is a good 1/2" of clearance under the case, too, which helps with the air flow. When my quad-core CPU is running at full tilt, I have never seen the case temperature rise above 32 C, and the processor itself has never exceeded 40 C. If you really feel the need for more air flow. there are two more places where additional fans cen be installed. (There are also two rubber grommets on the top of the case, which I assume are for liquid cooling setups.)

Finally, I find this case to be visually appealing, with a simple, conservative design. There are no clear windows, flashing lights, or other gimmicks that might appeal to younger users.

All in all, this is a great case that I recommend highly for any level of build experience. Its price point is higher than many budget cases, but take my advice and spend the extra $20.

5 out of 5 eggsSmooth as a baby's bottom

Pros: No sharp edges anywhere inside and out - awesome quality, included fans have 2 speeds (hi-low) and can be adjusted in the back-exterior, plenty of room for more fans and cable management is easy with the cut-outs

Cons: Case seems wider than the previous model

Other Thoughts: added a front intake fan and this thing is chillin, great airflow, kinda wish the hard drive rack was removable to allow better flow if only using a single SSD setup, had a micro-atx board in this case and it looked tiny so really made for atx boards imo.

3 out of 5 eggsDrive Rails could be better

Pros: The airflow spacing between stacks of HDDs is as good as any side-mounted drive-case around. Excellent airflow

Cons: Despite the generous width of the case, the drive-rails only allow one drive-mounting direction so both sides of the case must be removed for any HDD maintenance. If the drive-rails included all 3 peg-holes, drives could have been mounted 'tail out' so all cables AND drive-removal could have been completed in one direction - with less (or no) need to remove a case from its surroundings.

Other Thoughts: I can give a lukewarm Recommend as a big, heavy case for 6-8 HDDs but it's going to require more after-install maintenance due to the drive-rails' lack of peg-holes. Accessing SATA pedestals is overly difficult because of uselessly oversized motherboard tray. (The old Coolermaster 431 has a much better design.)

4 out of 5 eggsReasonable successor to Three Hundred

Pros: Supports USB3.0 and 2.5" drives unlike early Three Hundred cases. Good airflow and Sonata style drive mounting is convenient. Tool-less drive mounting seems to work better than some other brands.

Cons: Call me old-fashioned, but I like screw mounted drives. If they're going to offer tool-less drive mounting, please allow screws too. I also prefer card mounting that's inside the case like in the previous model (Three Hundred). Side-ways drive mounting limits the size of acceptable video cards.

Other Thoughts: I've built up two of these now and overall I like this case, but I'd buy the older Antec Three Hundred given the chance to buy one for the same price. I've built up at least a half a dozen systems in the Antec Three Hundred and prefer it to more expensive cases.

1 out of 5 eggsVery bad USB 3.0 ports

Pros: Enough big to have place to work in.
Very good airflow.

Cons: USB 3.0 do not works. One of the two ports do not work at all and the other one work only if i hold the connector at 90 degrees of the case faceplate, if i don't hold the connector the device vanish from Windows explorer. Also, it is hard to plug a device in these USB 3.0 ports, Antec did a very bad job with the USB3 ports of this unit.

Other Thoughts: Do you think i will ask for a new one, spend hours to remove components (i have a lot), and waiting a few weeks without computer and spend other hours to rebuild the system and after that a possibility to see that the USB 3.0 ports of the new unit are also bad. I have neck problems and all these hours will let me in a bad state for days. I did the build one time and it's enough for me. I prefer to buy something with USB ports that goes into a 5.25 inches bay. It's easier to rma it if it don't work.

5 out of 5 eggsA Solid Case

Pros: The case is HUGE and WIDE, mostly because it has a lot of space behind the motherboard mounting plate, to allow more room for cable management. It is built like a tank and the quality is top notch. I didn't see it mentioned anywhere on Newegg's product page, but the case actually has two fan control switches (high and low) on the back for each of the two case fans. At the low setting, when the case temperature is low, the fans don't even turn on, so it's really nice and quiet.

Cons: I wish the interior of the case was black, instead of the plain looking of steel.

Also, you know the place where all the PCI/PCIe brackets are attached to the chasis in the back? They're already secured with screws, so it's kinda weird that Antec decided to add one more bracket on the top to secure all the other PCI brackets. So to change a card, you first need to remove the two screws on this bracket before you can even get to the usual screw that holds the card in place.

Other Thoughts: This is the first case I came across that asks you to mount the SSD on the case chasis. For ~10 minutes, I was looking for a mounting bracket to no avail, and then realized that the four screw holes at the bottom of the case were actually for SSD. I guess this is not really a con.

5 out of 5 eggsBuilt Like a Tank!

Pros: This is my 3rd Antec 300 case. My last was the Illusion with 3 blue LED fans (2-120's Front & 140 Top) This is my favorite case of all-time! I paid short money after rebate ($50.00 with $2.99 Shipping) It's heavy & solid. It will fit most mid-high end GPU's length. You still get 1-120mm rear & 1-140mm top fans. They might (not sure)t be sleeve based fans, but they are reliable & quiet. I used Rosewill ROCF-11004 (Hydro-Dynamic Bearing) 120mm for the rest of the slots. These are outstanding fans for the money (when on sale) FILTERS! This is one of the main reasons why I love this case. Not many cases have a front filter (this is where I score the most dust) & the PSU helps as well.

Cons: Not much to complain about. The 2.5 SSD bracket isn't the best, but I purchased a 3.5 adaptor for this for $5.00 & all is well.

Other Thoughts: If you don't need all the flashy lights etc. & want a heavy old school & well built case then the Antec Three Hundred Two is the answer.

5 out of 5 eggsgood build

Pros: Nice looking case with a solid feel to it. It isn't garish, nor flamboyant. Neither is it gorgeous or slick. Its black, efficient, and simplistic with useful "to the point" attributes.

Extremely quiet with the two included fans on low, more so than my old pc case with "dampening cloth" installed, which cost twice as much, using an i3 and fanless gpu. Cable routing was fantastic, with tons of room behind the motherboard. Building was quick and easy, with only one caveat.

Cons: The mounts for the ssd were a bit troublesome to get situated. I wish I would have bought a PSU with more SATA power connectors, in retrospect.

Other Thoughts: This is my third build since 2008, and that being said I wish I would have just built with a variation of this case for all of those builds. This was easily the most painless case I have ever used to build a computer with. There were no headaches, and I was up and running in a couple hours. Temps are fantastic with a 750ti and i5 4590 with stock cooler, but honestly, I could have put those two into an ITX build and got great results.

I would highly recommend this case to anyone looking to build any type of computer.
