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'm not sure if this will ever be in stock on Amazon anymore, but it's probably still something you can find used, so I might as well review.I've had this case for almost three years now. I did experience some problems with the front USB ports for a while, as others mentioned. They cleared up eventually, and I'm not sure why. Maybe better drivers?Aside from that, this case is... well, it's a very functional case with all the basics that sits out of the way and doesn't try to distract you from whatever you're doing. If you find all the fancy RGB, glass-panelled modern cases distracting or gaudy--or need something you can set up at work--that's very good.The listed form factor is accurate (unlike OEM boxes I've experienced); it will fit an ATX motherboard e.g. the Z97 I have in it. Your power supply is meant to be attached to the bottom of the case and pulls in air from the floor, but a filter over that area prevents dust from getting sucked into your PSU and, for bonus points, this filter is easy to remove and reseat for cleaning. (Note: From experience, the Z87 Sabertooth motherboard does NOT fit. I'm unsure if other Z87 boards will fit.)But here's another important factor--maybe the most important if you're trying to build something with high performance: cooling. The ventilation is pretty good for what I've experienced. The foam-backed front panel lets a little extra air in around the hard drive cage and through any optical media drive slots you're not using, and plenty of air comes in from the side and bottom. It comes with two fans that work both well and quietly, and what I believe is meant to be an entry and exit space for a GPU liquid-cooling loop.The inside is fairly roomy, which helps airflow and allows more freedom in part selection. As far as graphics card length allowance, I recently had the opportunity to try putting a monstrous old EVGA GTX 780 Ti graphics card into this case, and it actually fit.One last thing to consider: cable management. This is partly dependent on whatever power supply you put in, but assuming your PSU's cables aren't a problem, this case won't give you a problem either. There's space between the frame and a side panel to tuck most of your cables out of sight. This isn't a shiny glass-sided case, so there's no aesthetic value to good cable management, but it does mean they won't do weird things to the airflow or get in the way during part changes and dust removal.Since I'm not interested in the cutting edge of modern hardware or flashy glass and lighting, and the fans can always be replaced if something happens to them, I don't see myself needing a new case for a long time. Unless something catastrophically fails or I need (and can afford) to build a second desktop for some reason.

I picked this case over the other ones because One: price is very reasonable. Two: Antec is a reputable brand, and had a case from them before. Three: it has black metal inside and outside, so uniformity is important to me, and it has clean lines, no fancy stuff. Four: It opens on both sides, so concealing wires is easier, and has a place for two more fans. Five: it has USB 3.0 ports in the front, which is an important part of my decision. I also went back to price too because most of the time I didn't need the fancy stuff, but I did need the USB 3.0 ports in the front. The front panel is a little difficult to take off, but as long as you are careful it will be no problem.

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!
