5 out of 5 eggs

Pros: This thing is a tank. Big and heavy, this case feels like it can take a real beating while keeping its contents nice and safe. Only one exception, see cons.

Looks cool- Looks aren't everything but its not exactly inconspicuous and its going to be sitting in your office, game room, mancave, bedroom, dormroom, etc for a long time. Best to have something you don't mind looking at every day.

Good airflow- Lots of well placed fans. There are more powerful fans out there, but the included fans are good enough for the vast majority of potential users, and very quiet.

Drive bays- Quite easy to remove and install, making assembly a breeze.

Cons: A few cheap parts- My first impression wasn't great when, while opening the side panel for the first time out of the box, the plastic part of one of the thumb screws disintegrated into several pieces between my fingers. I hear Antec is good about replacing stuff like this, but for now at least I just cannibalized an older case.

Cable management- OK, but not great. Requires a bit of creativity to get that clean look and maximize air flow.

Other Thoughts: Based on my initial impressions and other user reviews, I get the feeling that I will have this case for several years and multiple builds, making it one of the best values available.

4 out of 5 eggsGreat Value for routine builds

Pros: The case accommodates a high number of bay-mounted devices with lots of combinations of 3.5 and 5.25” sizes.
The case comes with 6 (3-pin) fans already installed with nice blue LED’s which work very well in terms of airflow versus noise.

There is a clip-on holder for an optional 120mm fan on the left panel (I bought a 120mm CM Jetflo fan to use there), and another holder for an optional internal fan to be mounted on the inside end of one of the 3 drive bays, making a high air flow conduit.

The case construction is solid, well-made, and had everything I needed and could imagine for the future. I consider it an excellent value.

Cons: While a full tower, the case length is a little shorter than other full towers that I’ve used, which gave much less room to work than I’d like between the motherboard (I bought the MSI Gaming 7) and drive bays. This made cable management between motherboard and drive bays troublesome, and made some connections to the forward edge of the motherboard more difficult. For instance, I ended up bending up the pins on the USB3 socket trying to plug in the cable required for the case’s front panel USB3’s.

There isn’t as much space under the right panel as I’d like for cable management, especially for the SATA and PERIPH (molex) connectors.

Mounting drives and devices in the bays requires old fashioned screws and screwdriver; this isn’t a big CON, but other cases I’ve used have nifty toolless methods (of course, they also cost more).

Mounting the 2.5” SSD in the spot designed for it on the bottom of the case was mildly problematic since all the cables of the power supply run right over it, and the SSD’s power and data connections get intertwined with them; I recommend buying a 2.5” to 3.5” adapter and simply mount it in one of the normal drive bays with the other HDD’s.

While the majority of the case construction is painted steel (making it relatively heavy), the top is plastic; the lip on that top by the front panel seems like a good handle, but I would not recommend using it since it felt like I could easily damage it.

Other Thoughts: I decided to use air cooling instead of water cooling on my CPU (i7-4790K), partly because I was concerned about radiator space and partly because I didn’t plan on extreme overclocking which would justify the need. I selected the Cooler Master Hyper 612 V2 (which worked very well btw); however its extreme height prevented the left panel from being replaced because the built-in fan clip hit the top of the cooler. I had to remove the Jetflo fan I had already installed there and remove the clear plastic section of the panel that had the clips in order to be able to put the left panel on. That left an air grate loose which I had to hold down by making a kluge of screws, washers and a paperclip. Further, the open air grate negates the value of the intake fan dust filters, so I used the Jetflo on the internal fan holder to make an air flow conduit out of the top drive bay right onto the memory and CPU (used the 2nd CPU fan connection on the MB), and adjusted the exhaust fans in order to produce a positive case pressure. While I’m OK with this configuration, I recommend using a smaller CPU cooler like the Hyper 212 to avoid this hassle.

The Gaming 7 only had one USB3 socket for the case’s three front panel USB3’s which required two plugs (one was a double). I bought a USB3 to USB2 adapter cable to make put the last front panel USB socket into service as a USB2.

Because of the high number of fans, I bought a molex to three 3-pin fan adapter cable to cover the three fans not accommodated by my motherboard. I recommend you use this on the 3 fans mounted onto the drive bays since you can use the extra slack when sliding these out; otherwise you might forget about the fan connection and yank on the motherboard connection when you slide the bay out.

4 out of 5 eggsOne COOL Case - Great Expansion Capabilities

Pros: This case has GREAT cooling, is open and roomy, and offers plenty of expansion space. You can officially put nine 3-1/2" drives in this case; 3 more IF you use the 5-1/4" bays; and more than that IF you get creative. It would make a great server or file-sharing case (if you have the room for it) due to the number of drive bays.

Superior air-flow and EXCELLENT cooling for your hard drives. The drive bay cages also have filtered intakes on the 120mm fans to reduce dust buildup and they work REALLY well.

Tool-free chassis, mostly.

Cons: Large (but you knew that, right). Drive cages must be loosened for filter cleaning and removed completely for drive insertion / replacement. That being said, if you don't constantly swap drives, this isn't a huge problem. Drives do insert easily and securely once the cages are removed, and the vibration dampening works well. Be sure NOT to loose the drive mounting screws as they are proprietary. I had to order an additional set, which to Antec's credit, arrived rapidly.

Cable management is acceptable NOT great. There is space behind the motherboard for some cables and some passthroughs BUT both could be improved.

Other Thoughts: I have owned this case since 2009 and overall, I love it. It keeps my components very cool - especially the hard drives. Since I run HDDs 24/7/365, this is very important to their longevity. I have some drives in this case that have been running nearly continuously for 5 YEARS! Each drive cage slots 3 drives with one 120mm fan to cool them. Personally, I just use the top and bottom slot (leaving the center free) as the static pressure of the fans is greatest at the outer circumference. I HAVE used all three in the past without a cooling problem.

I especially like the easily-cleaned drive cage dust filters, BUT wish the other intakes were filtered as well. You can greatly reduce dust build-up by creating a positive pressure environment in your case.

All-in-all, even after all this time, this is still a GREAT case for the money. It's especially great if you building with large, clumsy hands like some of us old-timers.

5 out of 5 eggsLove it!

Pros: This is a very spacious case; plenty of room for activities! It's got fans on fans on fans, so if you're looking to move air, this case is perfect.

Cons: The only one that really comes to mind is that the fans are all 3 pin. Back when I bought my Antec 900 for my first rig, it had 3 pin with molex, so you had a choice. This was convenient since PSUs come with molex power; however, since these didn't have that option, I had to buy an adapter to support all the fans since my motherboard only had 4 plugs to give. While this isn't a deal breaker, it was an annoyance because I had to order another part after assembling the whole thing. Just something to be aware of that no other review warned me of.

Other Thoughts: It's a great case. Aside from the setback of the fans, I didn't run into any problems with this case. Only the best from Antec!

4 out of 5 eggsVery Nice Full Sized Tower

Pros: Great tower with lots of bays and configuration options. Three intake fans, top fan and two exhaust fans, lots of great cooling. Bays have a good layout plus they are in three sections for easy in and out.

Great to have a back panel behind the system board for hiding all the wiring for a nice clean build.

System board used:
ASUS X99-A/USB 3.1 LGA 2011-v3 Intel X99 SATA 6Gb/s USB 3.1 USB 3.0 ATX Intel Motherboard

Cabling worked very nicely and matched up with no headaches.

Cons: The cable hiding panel, I needed a bit more depth to it, example the sata power plug cables from the power supply running up the back panel to reach the drive bays. Longer power cables with one or two leads would fix this though.

Other Thoughts: I used a CORSAIR Hydro Series H100i Extreme Performance Water/Liquid CPU Cooler. 240mm. I mounted it as a straight pull system using the already existing exhaust fans.

There is a nice gentleman that posted a video via Youtube on installing this and YES it will fit, just barely. Be aware that the tail of the cooler will cover the first I/O slot right below it. So if using more than two video cards this could be a problem.

Since this case offers an in out for two cooling hoses I plan on eventually replacing this with a full water block cooling system.

Also used:
CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Power supply fit fine in the case no issues.

3 out of 5 eggsDisappointing in support for closed-loop coolers

Pros: Light switch will let me sleep while PC is running in my room. 6 fans; takes a standard 120mm fan in the unused 7th fan port.

Cons: Claims of support for water cooling are deceptive.

Mounting a radiator in a drive bay requires drilling, and even then wouldn't put the radiator in series with a fan: the top fan is too far back, and the front fans are vertical while the radiator would be horizontal.

My Thermaltake Water 2.0's radiator doesn't fit in front of the uppermost rear fan (the top fan is in the way) or right against the back wall (the other rear fan gets in the way). Liquid cooling ports are provided, but they can't be used with a closed-loop water cooler (which would be possible if the surrounding grille unscrewed from the rest of the case and into 3 pieces).

3 out of 5 eggsGood case with only one solid complaint

Pros: great cooling, good size, and a awesome design

Cons: one of the four pegs between the ground and the bottom of the case is slightly shorter than the other three, causing the case to wobble if touched, not really a big deal but bugs the heck out of me,

5 out of 5 eggsLove it

Pros: Very Sturdy - STEEL

Rubber tips bottom

Comes with a few motherboard pegs

6 Fans are built into the tower standard with 9 being the maximum allowed in the tower.

Dial controls on the front 3 fans for speed settings and control

Cons: Heavy - as expected with a steel case full tower. I think i remember the shipping weight was 22 pounds.

Front 3 fans have a mesh net in front of them which holds dust really well. In my one month of having it my case has a white circle covering the fan that I've cleaned but attracts so much and since my rag is not damp, stays pretty well. Let me be clear, it does come off but fragments stay on it making the white color of dust stay. and it attracts it. Also to get to it you have to take out the hard drive slot it's attached to so just a heads up.

Other Thoughts: Over all awesome setup i built and I am happy with the case.

4 out of 5 eggs

Pros: Pretty spacious, lots of room to work with.
The fans are nice stock fans if you like the blue look.
Come with USB 3.0 in the top front.
Lots of drive bay space.

Cons: The cable management isn't as good as, let's say, a corsair case.
If you are looking for optimal cooling, get some better fans.
