Antec Gaming Series ONE Mid-Tower PC/Gaming Computer Case with 10 Drive Bays, 120mm Fans x 2 Pre-Installed, 120/140mm Fan Mounts, USB 3.0 x 2, 7 PCI-E Slots, Max CPU Cutout for ATX, M-ATX and Mini-ITX

The One is my third Antec case, and I shall start with some background about my experience buying other Antec cases for system builds (since 2004).Antec Super Lanboy (2004) 3.75/5The first was the Super Lanboy, which held up decently for a case that is necessarily flimsy and light--the clue to the reason for the use of thin aluminum is in its name--it was intended to be an easier case for a gamer to lug to LAN parties, and for that purpose it was suited. When I say that it is flimsy I do not necessarily mean that it was cheap--at no point did the actual aluminum parts of the case give me any trouble at all. The side window had chrome-looking "rivets" that were ultimately plastic, and a few broke due to their cheap quality. In addition, the rear fan used rubber screws that I unfortunately didn't at first know how to remove so I kinda broke the screws (I had to remove the fan to remove the motherboard). I recall sending an email to Antec about it but I do not recall receiving a response. As it was, I used twist ties like you might find on a loaf of bread to re-secure the fan (regular fan screws wouldn't have worked unless they were secured with a nut) and had no issues thereafter, including with vibration. The last issue I recall was that the front fan died (it happens) and I had difficulty removing it. I don't remember how that turned out. But the case was 3 years old by then and had overall held up well and I had overall been satisfied with my purchase, but decided to get a new case, and was focused again on getting an Antec product. Overall: 3.75/5Antec Nine Hundred (2007) 4/5My second case was an Antec Nine Hundred, which I loved. However I got into the bad habit of tripping over peripherals plugged into the various front and back ports and destroyed a front USB port that way (as well as a couple gamepads). Over time a short developed in the front audio out port and I will wholeheartedly assume it is due to my abuse. In addition, like all cases, over time it just becomes harder to clean, harder to get at the little corners full of dust, and to really get things clean you may have to remove fans that are not so easy to get at. A long story made short I wanted to replace the Nine Hundred because my own stupidity hurt its functionality and it was getting old and dirty because my computer is on 24/7. I can't identify all of the specific little issues that negatively reflect on the Nine Hundred (such as the fact that the top 200mm fan wasn't fun to service), but in seeing how no dust is accumulating on the front of my One so far, I have to say that the Nine Hundred just got so filthy. Moving air is always good but there are consequences for that and one is dust. To be sure, I'd rather have a dusty, dirty case that is cool than a tidy case that is hot, but I'd much prefer the tidy cool case. I will admit that I used to smoke right next to the case (and lived with cats!) and that surely contributed but even when that wasn't true and it was clean as reasonably can be expected, six months or a year later it was again immensely, ridiculously dusty. Much more so than I remember my Lanboy being. Especially when using front intake fans and multiple HDDs. That was where most of the dust seemed to end up. Just caked on the HDD, HDD cage, and HDD front intake fans. Ugh. If you've read this far just realize that the only knock I have on this case at all from my usage is dust. It's quite possible that once I got it dirty with cat hair and smoke being sucked through the intakes as that I doomed the case to always being dirty given that it just moves to much air. If you feel that way, feel free to consider me to have rated it as well as any of the cases that follow to which I will give higher ratings.Antec Three Hundred (2011) 4.5/5Between that second purchase for myself and this most recent purchase for myself I built a computer for my dad with the Antec Three Hundred and it is partly the fact that the Three Hundred was inexpensive but of good quality (and clean!), in addition to reviews from tech sites that made me go with the One. If Antec hadn't released the One I probably would have gotten the Three Hundred Two (update of the Three Hundred). The only other case manufacturer that caught my eye was BitFenix and if the cost of the One is about what you want to pay and you want to look at other well-regarded options, check out what BitFenix has to offer.Other (Various)I have done other builds over the years (for others) for which I did not use an Antec case. Usually this was to save money or because a certain form factor was required that Antec did not quite meet satisfactory. In those instances, I found nothing remarkable about the case, but neither did I encounter substantial cons. While I definitely prefer Antec cases because of the features you get for the price, the build quality, and the aesthetic design (a big selling point with me as I think most manufacturers make ugly cases, most especially when they are trying to use creative designs, with a few exceptions), I can't say that there aren't other decent choices at or below the One's price point.Antec One (2012) 4.5/5I have only had this case a few weeks and the only reason I won't give it a 5 in my written review (though I will round up for the Amazon's star review) is because I can be more precise here and this case is not perfect. Dust filters would be nice, as well as expansion slots that can be removed and replaced rather than punched out, but those are minor concerns and Antec can't deliver all the features a user may want in a budget case. The features that are here--rails for drives, a location for mounting an SSD (which I do not use as the Nine Hundred pre-dated SSDs and did not have a slot--I ended up using velcro tape to mount it to the right side of the Nine Hundred and have done so in the One) are nice features, and the build quality is nice, assembly was simple, and bonuses such as a USB 3.0 to 2.0 adapter are nice for those who don't yet have a motherboard with USB 3.0 support. I believe that a proper instruction manual doesn't ship with the case but is present on the website--however I did not need it. I have to say that so long as Antec (as well as its competitors) build cases of this quality and this feature-rich and sell them inexpensively I will prefer them rather than cases like the Nine Hundred (or its more updated models), which are 2-3 times as much.Final ThoughtsIf you want a well-made, quality case for a low price and are smart enough to avoid cheaper cases with bundled power supplies, the Antec One is as good as any for your money. I highly recommend this case and bought one for someone else the month prior to my purchase (I was still trying to figure out if I wanted for myself the Three Hundred Two or the One, as well as trying to possibly get the one illusion [which is identical to the One except it has more 'bling' in the form of blue LED lights]), and they like their case and have no complaints as well. Funny story: She moved her hardware from her very old case to the One and said that something was wrong. I didn't much wonder if the case was defective and with good reason: turns out she decided to pretty much randomly connect the connectors for the front panel for the power button, reset button, and LED indicators as if they are all interchangeable. They aren't. After fixing the problem, everything was fine and she loves the case.

I've been builing custom PC's from scratch for years, and have used Antec products before, but this is the best inexpensive case I've ever purchased! I bought it to use for a media server, and will be adding a 4 disk hot-swap drive cage to the 3 external bay openings. I think I'll still have room for a slim dvd option as well. Great fan placement options, with two inculded fans, bottom power supply placement for better air-flow, and plenty of room for all cable routing. I'll be buying another one soon to upgrade my personal system. Thank you Antec for the great design at a very affordable price point!

I bought this case as part of my first custom build.Pros:Its cheap.Mostly good construction.(see cons)Side panel vent compatible with a 120 mm fan for increased air flow.Enough hardware to mount and secure a full ATX board.Front panel USB 3.0 ports and audio ports.The case has some good basic cable management.Cons:The left side panel appears to have been damaged or perhaps has a manufacturing defect because it is extremely difficult to remove. I had a very hard time removing it with one hand. I had to use two hands just to pull it forward and then had to physically pry it away from the case just to gain access in order to install my motherboard. The only obvious damage I was able to find is a gouge just below the bottom thumb screw hole. To re-install the panel is also rather difficult. The top slides in rather smoothly but the bottom has to be forced in before pushing it back into place and even then it doesn't fit perfectly flush. But, the right side panel comes off very easily and goes back on just as easy.One of the front panel 5.25 bay covers don't sit flush with the rest of the case. this isn't a big deal at all but just more of a picky observation.The rear PCI expansion slots,with the exception of the first one, aren't reusable. Once they're removed they cant be replaced. This is only a real problem if you accidentally remove the wrong one or if you change GPU's from a a two slot down to a single slot.They don't give you any extra standoffs, motherboard screws, or thumb screws. Which was a problem for me simply because I accidentally dropped a thumb screw and it rolled under the fridge, which was my own fault. But so long as you don't drop or strip any you'll be fine.Conclusion:All in all this is a really good budget case. I considered returning it due to the panel issue but i decided it wasn't worth waiting for a replacement since the rest of case was pretty solid and I found that a pair needle nose pliers and a piece of tape to avoid scratching the finish can easily get the panel off. The only real con is the panel, but the rest of the cons I listed are only minor little things that aren't really a huge deal when dealing with a budget case. I just wanted to mentioned them so there aren't any surprises for any future buyers.I would defiantly recommend this case for those doing a budget build.

I bought this case as a replacement/upgrade when my last system died because of overheating. It's a bit on the large side, but that definitely works to its advantage.First and foremost, this case is cavernous on the inside. Plenty of room for drives, different form factor motherboards, full-length expansion cards, you name it! Another bonus is that all of the fan mounts are for higher-flowing 120mm fans. I believe there are five, in total: one in the top, one in the bottom, two in the front, and one in the rear (though I could be wrong about that). Also useful, the internal drive bays are oriented toward the side of the case, rather than the rear (making cabling less of a headache and likely improving interior air flow). Externally, the all-black theme is simple, yet elegant. And who can complain about having front USB 3.0 ports? Not I. Overall, it has solid build quality, free of vibrations and rattling typical of lighter-weighted cases. I am thoroughly happy with this product.
