No really, it's awesome. Yes, there are better cases out there, and if you're looking for an uberbad*** case you'll probably have to spend more money. However, the Antec 1200 V3 ranks up in the very top of cooling performance in almost any major case chart, so you do get what you pay for.

Honestly, it actually looks pretty cool, too. The blue case fans will light up a dark room, and you can turn off the big fan's light if it's too much. The case doesn't look like some freakish high-tech movie thing, which I actually like. It's still got more styling than 80% of the cases out there right now.

I've worked with many cases, and although this isn't the easiest case to work with, it's high up there. There's decent cable management room, and since the case is made of steel, you can jam cables into the "dark space" without the side panel bulging out. It's actually fairly roomy inside, too.

The only big problem this case has is the hard drive bay and front fan combos; in order to mount a fan in the front, you HAVE to have a hard drive bay behind it. This eats up space that could be used for a radiator, watercooling tank, or cable storage. It's a pretty obvious design flaw, but a minor one, and it didn't affect my opinion of the case overall.

Here's a comparison of my case temperatures. My old personal case was an Antec 300 with four 120mm fans and one 140mm fan. My new case is (obviously) an Antec 1200, with six 120mm fans, and the big boy 200mm fan.

Setup: ASUS P67 Sabertooth Mobo, i7 2600K @ 4.2GHz under a Corsair H60, GTX470 @ 10% OC.

My old case's temperatures usually looked like this....
Fans: All fans set to max speed.
Idle CPU ranged from 38-42C, averaged 41C.

I love this case! It was easy to assemble and came with plenty of hardware, screws and all of the fans needed. I was disappointed with the shipping quality as it was delivered to me only in the product package and not repackaged for shipping. The product box was destroyed upon receipt of the tower from the carrier, and I was not happy that the hardware box and cables included were not packaged for shipping. The box of hardware was just tossed inside the case and scratched up the inside of the tower during shipping. Big boy 200mm fan on the top has made a rattling sound since the day I fired up my system. I run this system with an

LG Supermulti Blu-ray drive
Thermaltake 650watt 80+ Bronze PSU
7x 120mm Antec Tri-cool Blue LED case fans

System runs great and was a lot fun building. The blue LED's are awesome and all match eachother well. I would only recommend getting a modular power supply because this case doesn't have the most room in the back panel for cables.

Had no trouble with cable management or attaching my MoBo, power supply, optical drive, SSD, video/audio cards. Super easy to get in and out of. Comes with extra screws. #2 screwdriver bit is all ya' need. Also, has an extra slot for a fan on the side panel. HUGE!

Downsides are there are not enough fan connectors on my MoBo to plug in all the fans with given cables. (more of a MoBo problem, but just a heads up that there are 6 fans, each requiring a connection. I managed to get 5 installed on my ASUS Sabertooth 990X R2.0). Also, the fans are somewhat noisy if in a silent room, but you put your headphones on or turn the t.v. on and its hard to notice. Maybe put some words on the one page of "instructions" provided. It wasn't rocket science to figure out but I am new to building computers so a little instruction goes a long way.

Of course none of these downsides are deal breakers, just things to be aware of.

If you want a big, spacious, blue case then this is the one.

I was getting so mad with my computer overheating and shutting down, so I went for all out cooling and bought this gigantic case. No regrets, however some design changes are definitely needed, hence the -1 star. I have described below.

The filters are a fantastic idea with supposed easy removing capability. However, there needs to be a latch on the OUTSIDE to remove the filters, not opening the case and removing 8 screws to push the container out to clean one filter.

Very very VERY lazy USB 3.0 connection on the front panel. It is basically a plug that connects to the back end USB 3.0 output of the motherboard, so all it does is replacing the back USB 3.0 connection on the back and putting it on the front. It should have connected directly to the motherboard. Lazy way out on this.

At this price point, there should be a digital display as well as a digital way to control the fan speeds (though the manual fan speed control is nice).

To sum up, very nice case, but you can tell where the designers got a little bit lazy and rushed to complete this case.
