5 out of 5 eggsCase and fans

Pros: Very good case and design. Has lots of room for just about anything you could want to put in there.

Cons: There has been nothing bad that has happened so far with the case.

Other Thoughts: This case does allow for a 240 liquid cpu cooler radiator to be mounted in it. At the top of the case there are 2 120mm fan mounts and those allow for the radiator to be mounted. I did that in my computer build and it works just fine and be sure to have the fans push air out of the case instead of pull in because it will cause the comp. to overheat. (hot air rises, cold air falls)

1 out of 5 eggsSTAY AWAY

Pros: None at all !

Cons: Looks like it was painted with a brush, It actually was in several spots. Mfg. touched it up where it was scratched. Thinnest sheet metal of any case I have ever owned, even seen. Tool free design is only partially tool free, screws must be used on one side, or purchase more mound brackets. Zero help from Mfg. When I contacted them about this they thought wrote back calling my email spam. When I wrote back they didn't respond.

Other Thoughts: I could go on and on about this product but I wont, just beware. Not what is pictured AT ALL !!

4 out of 5 eggsGreat looking case for my 9 year old boy

Pros: Case looks great. Motherboard fits in easily. Plenty of room. I like that it has USB 3.0 on the front panel.

Cons: 3.5 in drive bays when loaded block the installation of a fan. One of the fans on top is blocked by the 8 pin power connector on the motherboard. Maybe that is the design of my motherboard.

3 out of 5 eggsCase Received

Pros: Looks nice, Nice shade of red for the steel part, but that the tricky thing is in the picture the plastic part has the same shade of red... When you get the actual case you will see that the plastic (Front part) of the case is actually a different shade of red.

Cons: A shame that it doesn't come with any SATA cables.

1 out of 5 eggsCheapest case I've ever owned

Pros: - Pretty and red
- Decent cable management

Cons: - Cheap stamped metal. The back PCI-E slots covers are permanent until you break them away from the stamped metal frame of the case. If you break out the wrong one, you just have a gaping hole in the back of your case forever, unless you have some leftover covers from older cases.

- Does NOT support graphics cards longer than 10'' (~250mm). The HDD cages are permanent and, despite its claims of supporting up to 12'' video cards, it largely depends on the geometry of the card. Tall cards (such as the GTX 780) WILL NOT FIT.

Other Thoughts: My wife really wanted a nice pretty red computer case for her computer. I managed to catch this one at around $35 (after a MIR) so I figured, what the hey, it can't be that terrible!

It was.

It is hands down the cheapest case I have ever purchased - and I don't mean in cost. Everything about this case feels like its seconds away from bending, breaking, or just plain falling apart. Most of that I could've dealt with simply because of the price (though I have purchased better manufactured cases for less) but the final straw for me was the incorrect, or at least misleading, advertising.

Newegg's specifications on the case say that it will support graphics cards up to 12'' in length, though it may block access to HDD cages. Thats fine - except the problem is you would have to have a very specifically manufactured 12'' card to get it to fit inside the HDD cage. If you have a video card with a rectangular build (ala EVGA ACX cooled cards) then the max length you can fit is UNDER 10.5'' - the average length of ACX cooled GTX 780's.

And its not just EVGA. I also tried to put in a Sapphire HD 7970 Ghz edition which was 11.5'' in length and while it had a much narrower back end that let me attempt to wedge it inside the HDD cage, it still DID NOT FIT.

If you're looking for a cheaply made case that doesn't have to support high end video cards and is a very pretty red color, this case is for you. Otherwise, stay away - there is nothing for you here.

3 out of 5 eggsGreat space, nice cable mgmt, very plastic

Pros: Great space, the cable management works great

Cons: I didn't think it was so plastic. I wanted a great case and the flashy red was nice, but it feels quite cheap

Other Thoughts: I wanted something nice looking and it is.. however the plastic feeling makes it feel cheap and not so sturdy. Not a bad product for the price though

4 out of 5 eggsSolid, cool looking case

Pros: -Looks nice
-Good cable management options with space on side
-USB 3.0 in front

Cons: Never managed to get one of the panels off. My wiring looks awful :(

Other Thoughts: Assuming the problem I had with the side panel doesn't occur for everyone, this is a great case, and I would definitely recommend it.

3 out of 5 eggs

Pros: Great Design, plenty of drive bays for some like me who does a lot of CADing.

Cons: Cable management was very difficult.
Front door started to give out after about 1 month, pins that held door together fell out (hard to fix...)

Other Thoughts: Liked the look of the case, although, in reality was a midline case. I paid ~$55 for it, could have gotten way better value out of a cheaper case like the Cougar Archon (less drives, better overall)
