Antec Twelve Hundred--Unpacking And Build

Four Full Tower Cases From $150 To $600


Side shot, with hardware installedSide shot, with hardware installed


After the majestic-looking brushed aluminum Canyon, any other chassis would have a hard time sizing up—that is, until you start taking price into consideration. Antec’s Twelve Hundred can almost be considered something of a reference standard by which to measure other towers, thanks to the company’s history of designing functional, inexpensive cases. And with a price tag under $160, you could buy more than three Twelve Hundreds for the price of a single Canyon 695. Suddenly, we’re a lot more interested.

Puling Antec’s packaging open reveals a plastic-wrapped tower sandwiched between foam—and not the kind that crumbles apart when you try to pull the case out, either. Two thumb screws hold each side-panel in place. Pull off the instruction manual taped to the side, open the left panel, and remove the small accessory box. Antec bundles cable ties, plenty of screws, washers, and an adapter for turning one of its 5.25” externally-facing bays into a 3.5” slot.

Like the Cooler Master case we’ll be looking at next, Antec opts for a more open design, enabling plenty of airflow at the expense of acoustic insulation. The entire front, most of the top, a triangular section of one side panel, and much of the Twelve Hundred’s rear is covered by a metal grille. A slow-spinning 200 mm fan sits under the top of the case, three 120 mm intake fans pull air in through the front, and a pair of 120 mm exhaust fans in the back push warm air out. All of the fans include blue LEDs for an extra bit of visual flair, but for the folks who’d rather not boast the bling, they can be turned off.

Although certain pieces of the case are clearly plastic, the rest is built using steel—and the shipping weight of 42 pounds reflects this. Not that you’d want to lug any of our four featured chassis around to LAN parties, but the Twelve Hundred in particular is a herniated disc waiting to happen.

Front-panel connectivity is on show, front and center. Like most of the other towers we’re seeing, power and reset switches are up at the top in easy reach. Between them, you’ll find USB, eSATA, and audio I/O. The left side panel is windowed, providing a glimpse into the wonderful world of your hardware. A fan bracket mounted to that same panel accepts an extra 120 mm cooler, if you see fit to add it. Around back is where you’ll find fan speed/LCD controls, cutouts for water cooling components, and seven expansion slots (that’s right—no room for three GTX 280s, if that was what you were planning.

    Thank you Chris, another very useful article. Not enough case comparisons around, as I'm sure you realized.
    I'll be sure to add the HAF to my recommendation list. I hadn't before because I thought all the extra holes would hinder cooling more than help. The hole in the MB tray sounds especially useful.
    I would have liked to see on of the Cosmos cases included, although I suspect they are simply quieter but hotter.

    Nice article.

    Though, I'm curious. 40db+ isn't whisper quiet. That's freak'n loud. What's up with calling it whisper quiet?

    The three cheaper cases are powerhouses but too big and overkill for most people including gamers. I think the Antec's Three Hundred ($60 a few weeks ago on Newegg) suits the need for most people. 750w PSU are usually enough for SLI/Crossfire so 1000w+ aren't needed.

    I'm curious when they will start releaseing more cases that have more depth, so that they have more room for today's much larger videocard solutions.

    Ya I agree that case designers should consider making them have more depth. With this in mind though i'm sure vidoe card manufactors will only make their card even longer however.

    Lian Li has plenty of depth, and otherwise just huge (PC-A70).

    Good article. Now it gives a procedure and template to test other cases as well. It'd be great to have a review of cases which could be "best of" a certain category (cooling, noise, ease of use, weight, etc). It would be even nicer if the results were put in bullet point form and were setup in a table like the ones used in hdd/video card tables. That would make it a lot easier to compare everything.

    I do believe that all the cases available in the market these days are poorly designed especially when it comes to air flow. You may notice that front fans, rear fans, buttom, side and top panel fans -when combined- cause turbulence in air flow that reduces the overall air flow. That's why I buy a cheap $25 case and modded myself!!!
    I have so many innovations regarding case designs that I hope someone buys them and excutes them in reality!!

    Here is one of my ideas...
    To put it plainly: air needs to be moved in one direction, preferably from down-upwards, since hot air tends to go upward by nature and the hottest part of any system (that's the GFX cards) is located at the lower part..Hence a PSU mounted at the upper part of the case (with its 120-140mm fan), with another 120mm top-panel exhaust fan and two 120mm buttom intake fans will be by far more efficient than all the available cases. To achieve this efficincy I close any other holes (even the ones the manufacturer meant for ventilation) so the air enters the case only from the buttom fans where I put dust filters to minimize dust inside my case. Furthermore I use a case with long "legs" to minimize inhalation of the dust at my desk's surface.
    To minimize noise: I use
    1.low RPM silent fans.
    2.rubber washers between the fans and the case to minimize vibration noise.
    3.cover all the interior surfaces with a layer of an insulator, that can be as simple as sponge!!!
    4.even design external air ducts that divert the exhausted air (which carries the interior noise) to the back.

    Fortunately many aftermarket CPU and GPU coolers helped me. They can be installed in a way that the fan moves the air upwards. There is evidence that the setup I suggested above reduces -though marginally- the power consumed by the CPU and GPU fans to reach thier designated rpm and increases the lifetime of these fans, since instead of meeting resistance, the one directional air flow helps them.

    I'm curious about putting sinulation in a case. I'd love to see measurments of noise levels in a case with just random sponges in the case versus not.Heya,

    I'm curious about putting insulation in a case. I'd love to see measurments of noise levels in a case with just random sponges in the case versus not, and other solutions. Personally, I don't like lights and other stuff in the case, I don't look at my case, I look at my display. Reducing the case's obvious footprint and pressence is a nice thing. Less noise would be wonderful (especially since I use mine as a HTPC too). I've always been a fan of the blow hole (top fan to draw hot air out). Sealing up a case to reduce all holes to just air flow from bottom to top, with insulation of some kind to reduce noise would be a great project to try.

    Again, I'd love to see some noise and temp measurements! To the forum? Got some ways to measure it?

    Believe it or not the setup I mentioned keeps my E6750 (overclocked from 2.66ghz 1.23v to 3.8ghz 1.44v) under 55 c under full load (hours of dual prime 95) in a very hot room that lacks a cooling system(temps:40 to 50 c !!). (Don't be smart with me, we lack electrical power in my country and private small-groups generators are the only reason I can be online!!)

    I don't have the means to measure the noise level but I can tell you -though subjectively- it is very quiet when using all the mentioned steps. In the end I wish someone with enough resources (like the guys at Tom's) tests my project and give the whole world accurate objective measures and compare them to the available cases..Even the high end ones.

    In my last post I forgot to add that I use vertically-oriented Zalman CNPS 9500 LED as a CPU cooler.

    600$ for a case? hahahahaha

    almost spit out my drink when i saw the price tag

    They should make an article on water cooling for the i7!

    Getting there. Gotta remember that i7 is still new, so there aren't a ton of options available yet.

    Good write up. But should have increased the # of cases and droped the range to a max of $350-400.

    Kept the number lower so I could spend more time with the cases involved--takes a deceptively long time to build each system up, test it, etc. The ABS case is actually the one that set the whole roundup off--it was a struggle finding enclosures that could compete. I think we'd all love to have that thing, but the price is just prohibitive. Even still, very nice to look at.

    Wow, those are four hideously UGLY cases... I'll stick with the Cooler Master Cosmos series.

    Okay I'll bite:

    1.low RPM silent fans.
    2.rubber washers between the fans and the case to minimize vibration noise.

    Okay, these 2 ideas are pretty well established. Although personally i have doubts about #2 really making a difference.

    3.cover all the interior surfaces with a layer of an insulator, that can be as simple as sponge!!!

    Right, but it can also be as simple as extreme fire and inhalation hazard. Make sure what you are using doesn't burn easily.

    4.even design external air ducts that divert the exhausted air (which carries the interior noise) to the back.

    This may seem like a good idea on the surface, but by restricting the air flow (you build additional pressure in the outlet) you might actually be increasing fan noise and heat buildup.

    High legs are a good idea to prevent dust (i have this problem as well) but can be dangerous for someone who has the case on a carpet or other uneven surface, since it increases the chances of the case tipping over.
