1 out of 5 eggsOverpriced Junk

Pros: Arguably lots of room in the main area. With all the doors open, there's plenty of space for hot air to escape.

Cons: Not enough cable management; rear of the case has little room to stow cables; top portion of case doesn't have enough access from the main body; flimsy construction; side-hanging doors from top have problems locking; side panel doors of main body have problems locking; hot-swap is useless since the backplates are defective.

Other Thoughts: The case should be a serious contender for the Haf Stacker. But it's not. It should have been an easy to fully customize the case, but you're left scratching your head trying to make the cabe management work properly. The front IO is horrible. The power and reset buttons are extremely flimsy--after only a few day's worth of normal use, the buttons are getting harder to push and often require repeated pushes to activate. The stupid feet that come with this case are incredibly irritating. Because of the immense size and weight, you have drag the case to pull it out of a corner. But if you do that, the feet slide back and off. For the price of this piece of junk plastic case, the feet at the very least should have been secured to the bottom of the case--putting a couple of screw holes wouldn't have cost anything.

I run a tri-fire rig with plenty of fans. But with the case closed there's little to no airflow. In order to get any cool air inside, all of the compartments have to be open. For those who don't intend on OC, it shouldn't be a problem. For I suspect most people will buy this case for the thought of modifying and OC.

I am very disappointed with this case. The build quality is rubbish. The "expandability" is severely limited due to the lack of sufficient access within the case. I could overlook these issues if the case was 1/2 the price. But at its current price point, it is a rip off.

I'm going to purchase a CM ultra case instead, and use this plastic box for storage--how unfortunate it is an expensive plastic box that can't be used.

But at your own risk. Or, be willing to spend a lot of time and effort making serious modifications to the unit.

3 out of 5 eggsA case that needs work

Pros: 1)Vast amount of space
2)Lots of fan mounting options
3)Hot swappable HDD/SSD bays
4)120mm based water cooling radiator mounts
5)Dual power supply mounts
6)Dual motherboard option

That being said, if you are looking for a massive tower this could be a case for you. There is plenty of consideration given for airflow with this case. It supports the largest motherboards (GA-X58A-UD9) out there for the main system and also an area for a compact motherboard.

Cons: 1)Wires were broken to the reset and power switches
2)The USB 3.0 interface was broken off the front plate
3) the USB 3.0 cable does not have a typical USB interface to the motherboard
4)The mounting posts for the motherboard are to tall and had to be ground down for the motherboard so that the motherboard would fit the rear plate and for the pci cards to sit flush with the rear expansion slots

With all the options that give it pros unless you are handy these cons would warrant a return and you would have been stiffed the cost of shipping to and from. I have soldering experience and metal working under my belt so I was able to to make the modifications and get the case to work for me. I am not sure what the company was thinking putting the USB 3.0 cable from the face plate with some weird unconventional plug that does not work with a standard USB interface found on motherboards. My Gigabyte GA-X58A-UD9 has a USB 3.0 plug on the motherboard but the current cable will not work so I either have to cut the end off and adapt it or not use it.

Other Thoughts: I was looking for space and that is what I got this case for. I would not suggest it for someone new to building computers. You should know how to solder and rewire to make the USB 3.0 cable work for you. I took two stars off because of the low quality of the construction, ie the motherboard fit was poor, the non-standard USB 3.0 cables, and the broken wires to the reset and power switches.

5 out of 5 eggsGreat Case

Pros: This case is huge! well ventilated, great quality case. It also keeps dust out.Me and my wife own 4 cats no fur in side.

Cons: THIS CASE IS HUGE, its heavy. lol plus and a negative i guess. the only thing so far is on the back the screw holding in the side panel has a one of tighten with your thumb heads on it and it broke off.. no big deal i will just need a screw driver for that one screw

Other Thoughts: Over all I would recommend this case to anyone who wants a computer with that stays cool, clean and last. Installation inside the case was super easy as there is so much room to work with, you can run the wiring through the back of the case very easily to keep it from cluttering.

2 out of 5 eggsawesome theoretically

Pros: two systems, making it perfect as for server prototyping and server/client building applications, lots of hot sway bays making it great option for applications involving personal harddrives
i love the liquid cooling options and the two sections

Cons: for starters, heat rises. so most of the heat from the lower section is going straight up to the top section, strongly recommed anyone using two systems, do strictly liquid cooling.i used the top section alone for awhile cause mini itx was all i could afford. the single expanison slot on the top section limited the selection of graphics card i could use in it, so i ended up moding the cooling block on a decent vid card to fit, but i was forced to leave the side panel open while i had it. i installed fans on all the areas i could, but the fans on top were always vibrating against the vents making it very loud even with sound damping, the hdd bay is place very poorly, when you plug in the sata cables the back of the plugs press against the side panels to a point it puts pressure on the circuit board and even bents the plug, cable management was a nightmare, as the i have a hard time fitting the plugs through the small holes . while i was moding the build for my new desk i noticed the top half came off completely but you cant use the two sections independently . and last but not least, i noticed alot of mother boards have usb 3.0 plugs, i noticed the top section doesnt, if any of you buy this case, make sure you get a smaller psu, as only a mini itx sized psu well fit in the top section (think 600 watts max

Other Thoughts: over all a regrettable buy on my part since it seems i'll never get around to using the button section, but strangely enough the motherboard im using seems to prefer this case over my new case, as its been having power distribution problems since i changed cases, and fyi i added 400 more watts to compensate for the problems , with no effect

4 out of 5 eggsaza fusion 4000

Pros: very large case with an endless list of possability. I think i got the very last one available because everyone is out. It has a very large area to add just about anything you want. If azza keeps building cases like this i will always buy from them.

Cons: after i paid for the item, newegg kept me up to date on status, took them 1 week to package the item, but it arrived the side window was scratched up and the box it came in was the origanal azza case box with shipping lable? why did it take a week just to put a shipping lable on and ship it? (but ill tell you one thing, i called newegg for help and they couldnt help but told me to call azza. I did just that and they said they will mail me a new panel. thankyou azza i will be a loyal customer for life, i will be purchasing 2 more( different ) cases soon for my other builds

Other Thoughts: when i complete all my purchases i will upload video of my build

4 out of 5 eggsGood if needed

Pros: Can hold dual systems and is great for water cooling options. All drives are hot swap which turned out to be quite handy. Lots of room to put what ever you want plus more.

Cons: It is REALLY heavy (Although that is kind of expected). The build quality is not good, at all. The clip/handles for the top compartment are horrible, I literally have to bang the doors closed for them to set right. Additionaly, the thumb screw that hold the top bezel on has never fit in its designated hole. The front fans are blue, I would of liked them to be stock red to match the case paint (Although this is more of a preference and is not that big of deal). The hot swap bays are really bad, it takes way to much effort to ensure your drives are connected to the back tray, the trays are also in painted (The drive and cage blocks this from view). The sliding mechanism that alters the degree of the top vents squeaks and can get annoying especially when using them a lot. I would of also preferred that the top 2 drive bays be single slots each. Only one of the front control panel has USB 3.0. A big problem I also ran into is that the top compartment only has a single slot GFX slot.

Other Thoughts: If you need two computers in one case like this then it is the one you need. If you need the extra water cooling space then this is also a great case. But if you don't need either of those then I probably avoid this case as it is definitely not worth 280$

5 out of 5 eggsHUGE TOWER!

Pros: So much space for accessories, great setup for wire organization, space for 2 motherboards, wide enough for any aftermarket cpu cooler of any type, quick connect for HDD or SDD, external usb 3.0 connections, room and pre drilled holes for a ton of extra fans, 2 sets of power controls if you want a second motherboard, and on and on and on.....

Cons: shipping is pretty high

Other Thoughts: I absolutely love this tower. There is a view window on the left side albeit a small one.

4 out of 5 eggsNice case

Pros: Wide open space, nice drive storage arrangement, Dual systems! very quiet fans.

Cons: The smaller bay's for the 2.5" SSD's didn't work :(, had to bypass them. It would be nice if there was a built in KVM switch????

Other Thoughts: All in all i am very pleased i look foward to loading the mini ITX board latter this year for a (test) machine.

5 out of 5 eggsShipping

Pros: Huge

Cons: Shipping

Other Thoughts: Would buy in a heartbeat if I could pick it up in GTA warehouse. 70 dollars is more than I am willing to pay for shipping esp when GST is added on top of that as well. Would be exactly what I need.
