Assembling the Antec Three Hundred Two

Given that the Antec Three Hundred Two is a fairly simple and staid affair to begin with, it stands to reason assembly would be just as simple and staid. That's mostly true. It's not as easy to put together as something from Corsair might be (currently my standard for ease of build), but it's close enough.

Antec graciously has four motherboard mounts already in place, something Cooler Master couldn't be bothered to include in an enclosure four times as expensive, and once again it's a small touch but it's a welcome one that speeds up the assembly. Where things do go a little bit south is in the wiring for the two Antec TwoCool fans that are included; their fan controllers are both externally accessible on the back of the enclosure, but the 140mm fan requires a four-pin molex connector while the 120mm fan's three-pin cable is too short to actually reach the fan header on the motherboard. As a result I had to use an adaptor cable I had laying around to actually wire the rear fan. Obviously, choice of motherboard plays a role here, so YMMV.

Nearly everything else after that point was smooth sailing. The toolless rails that Antec includes for mounting 3.5" drives are slick pieces of engineering; they slot into the screw holes on the drive, but you can actually pick up the drive by the rail and it won't fall off. 5.25" drives also benefit from a toolless locking mechanism that's among the best I've seen in the enclosures I've tested, feeling remarkably secure despite only locking in on one side.

The two places the assembly got at all hung up were the 2.5" drive mount on the bottom of the enclosure, and the metal extrusion from the motherboard tray that holds the power supply in place. I'm still not a fan of having to screw a 2.5" drive into the bottom of a case, and there's just no good way to orient it. If you face the drive's ports to the open side of the case, there's barely enough space to get a power cable in there, much less a SATA cable. If you face the drive's ports to the back of the case, there's no cutout in the tray to route the cables and you have to feel them out.

Mounting the power supply was a bit of an ordeal until I just grabbed a pair of pliers and bent the metal extrusion upward. It took some pressure off the power supply, but also allowed me to fit the thing in there to begin with. Problem solved. Again, component selection could help here; our SilverStone Strider 750W PSU is by no means massive, but it is 180mm while other PSUs are only 160mm.

Wiring everything up after all of this was mostly a breeze, though the Three Hundred Two would've benefitted from slightly bigger routing holes in the motherboard tray. They're rounded off to make things safe, but they could stand to be larger. That said, most of the complaints in assembly are minor; the Three Hundred Two comes together quite well, and getting the back panel on was surprisingly easy. Where assembly is concerned, the Three Hundred Two is a smart design.

    I have actually drilled my own water cooling ports on my older Antec 300, PM me on the forums if you want to see it. So yes they're good to have. Unusually placed on the top, the rear is much more normal. Glad to see they fixed the major flaws with the old Antec 300, but really they could have gone a few steps further and painted the inside black as well as offering a windowed version. An improvement, but not worth paying $80 imo, there are other better cases out there.

    ...to take the original 300 and make it look like crap. I'm saying this purely from an aesthetic point of view and I'm specifically referring to the the curved front. It seems to be what Antec is best at these days considering the hideous DarkFleet series, the LanBoy Air and also the new P280. It's a shame....

    That's exactly what I was thinking!

    The only thing I didn't really like on my 300 was the pair of protrusions on the front. So they made them even bigger! XD

    I hope that either the USB 3.0 panel fits the old 300 or the 300 plastic front fits 300-2.

    yep.
    the curved front is my greatest issue with this case too.
    the rest of the case on the other hand, is to much of an improvement over the 300 to not put it on my shortlist.
    and pretty high on that too.

    still, i would like to see the 300 bezel on the 302.

    why bother reviewing full-size atx cases?

    who buys these clunkers?

    what percentage of people need atx over microatx? why? and for the masses, mini-itx...

    Are you being serious?
  • bnolsen - Thursday, January 26, 2012 - link

    mostly agreed, but the old 300 is excellent for holding a small raid array excellent drive cooling, etc. I was hoping antec would release a microatx version of the 300 (same number of hard drive bays, dump the extra 5.25's).
  • ZekkPacus - Sunday, January 29, 2012 - link

    The issue is that most hobbyist builders won't have great cable management skills, bigger cases are easier to tidy.

    Added to that, I'll always have full ATX cases. Granted I only run a GPU and a soundcard nowadays, but spacing them out makes me happy. Show me a MicroATX case that has thermals equivalent to an antec eleven hundred/p280/corsair carbide 500r, and as much cable management.

    The P180 mini isn't far off but have you seen the size of it? It's more or less a mid-tower case. Added to which it is now badly out of date.

    I have a Three Hundred that I am very happy with. Only downside is the fan noise, which is kind of inherent in a well-ventilated steel case for gamers. Its nice they went to USB 3.0, and made the side panels easier to attach. Very solid case, easy to work with, and keeps a gaming rig cool and stable.
  • nikhil2004 - Wednesday, October 1, 2014 - link

    i brought this cabinet and i m satisfied with the performance.
    unfortunately this one is no longer available, never the less almost all antec products are eequally good...
    i bought it from martnext.com gave me best price along with COD facility
    try out yourself for best deal on Antec products
