4 out of 5 eggsGreat budget case when on sale

Pros: Cheap
I love that the drive bays face outwards. Luckily more cases are doing this now.
Nice design

Cons: Interior should be painted black!
Very little room for real cable management

Other Thoughts: Overall it's great! I recommend this case to my friends when they are building a cheapish gaming computer. I say it gets the job done.

Only issue I have is I was recently cleaning my fans and one of the blades broke on the back one. Very sad. So I'm off to find a replacement.

4 out of 5 eggs

Pros: Plenty of room for expansion; excellent air flow

Cons: Front USB panel is broken. I submitted a ticket with Antec 2 weeks ago and haven't heard from them since.

I checked Antec's store and every other place I could think of, and nobody seems to carry the front port assembly for this case.

3 out of 5 eggsIt's a case.

Pros: Sturdy

No paint inside for better grounding on motherboard

screwless hard drive bays and cd drive bays

usb 3.0

Cons: bad cable management

Small, I wish it was a full atx tower

only comes with 2 fans, both in the back

Other Thoughts: The cable management is pretty bad, I can barely fit the 24 pin power cable back there.

5 out of 5 eggsGreat case!

Pros: I bought this case as a part of my Christmas build and didn't think much of it. It was just a case, and I needed one. After some months and thinking about upgrading my gpu from a 560ti to a 670ftw I got worried because people were saying that you will need a full tower to fit the 10 inch card. That was not the case for this case(hehe, case). This case can fit cards up to 12.5 inches; that is pretty big for a mid tower case. Also the installation for hard drives is the fastest I've seen. You literally make a hard drive sandwich with the plastic holders and slide it in. It snaps and is very secure. It is very quiet, and not noticeable at all when I play. Once you push the fan up to around 65% 70% you will begin to get a hum, but it is only bothersome for a few seconds as you grow used to the sound change. If you use headphones it goes unnoticed.

Cons: The only cons to this case are ones that are effect people in specific situations.
My case came with the power button(not the tab you press, but the actual button that the tab pushes into the case) came to far inside the case. When I hit the power button it wouldn't actually attempt to power on, it took me about 20 minutes to realize that the inner button was jammed. It only took one attempt to free it up, and it has worked flawlessly since then.

My only other issue is that their is no adapter or anything for an SSD, so I was forces to cut a piece of cardboard to hold it in the case. That and some duck tape to secure it. It may sound odd, but it has worked perfectly.

3 out of 5 eggsNo longer supplying USB adapter

Pros: Great build quality
All-Black model with black interior and additional fans is a nice option if available

Cons: No included USB 3.0 > 2.0 adapter
SSD mounting is awkward, seems like an after-thought

Other Thoughts: As others have stated, for 2012 Antec was supplying, free of charge, a USB 3.0 to 2.0 adapter. However, for 2013 this is no longer the case (no pun intended).

Customer Service referred me to their Antec Store to purchase the adapter, stating that in 2013 they are no longer supplying them free of charge. Antec Store only ships to US (even though it specifies US/Canada), pointed that out to the CS rep, was then referred to their 800# to purchase it.

Final price for the adapter is $4.95 + $5.00 shipping (to Toronto), USD$.

For the list price, plus $10 for the USB adapter, you can purchase a much nicer case, or stick with the original Three Hundred model (or TT v3 case) and save some cash.

As an owner of a half-dozen Three Hundred cases, and now one Three Hundred Two, I wouldn't recommend this particular product at this price point, if you require a USB adapter as well.

5 out of 5 eggsThere is a hole to route your 8-pin cable

Pros: -Great value oriented case however this does not deserve the "gaming" classification as this case does not have sufficient airflow to cater to gaming users. I would argue that it would be more of a business oriented case suitable for internet cafes or office environments.
-cost
-features

Cons: -No included front fans or extension cables for front fans.
-SSD mount requires you to install the SSD first before installing the motherboard on the back panel.
-Interior isn't painted
-Side fan panel for the cpu cutout blows dust into the case.
-Heavy
-Lack of top ventalation for additional exhaust (only 1 140mm fan rather than providing the option to purchase another 140mm fan for better airflow/heat dissapation).
-140mm fan is noisy at high
-no 3.5 bay for aftermarket card reader/usb panel

Other Thoughts: You can route an 8 pin cable from behind the motherboard. If you look at the right side of the case where the cables are stored, there is a slot at the top of the case where it is just wide enough to feed your 8 pin power cable through. Once you slide the connector through, you can slide the cable to the right hand side to connect the motherboard to the power supply.

alot of users have missed this and it is not mentioned in the manual.

4 out of 5 eggsPoor Support

Pros: Room for several case fans.

Cons: Front USB panel does not function; I've been waiting MONTHS for Antec to send a new one. So far, they've just been sending excuses!!!

Other Thoughts: The case I like the customer service I don't.

Manufacturer Response:

5 out of 5 eggsGreat Case for the Price

Pros: 1. Dust Filters for the front intake, and bottom PSU.

2. Lots of space, inside there is lots of clearing for Graphics cards of any length, and behind there is lots of room for routing cables.

3. Solid build quality, just like Antec.

4. Keeps system very cool, nice to have 2-speed fans in the rear and top ( I keep them on low ).

5. Cool positions for mounting SSD drives.

Cons: 1. No mounting holes in the front for 140mm fans, only 120mm. And the holes are small, so be aware when buying new fans for instalation.

2. No intake fans included.

Other Thoughts: This is a great case especially for the price, I bought an Antec Truquiet 120mm fan to use as an intake on the front, had to make the mounting holes bigger by bending them in order to use the rubber tubes that hold the fan in place.

Upgraded from an Antec 900 ( first generation ) . Planning on mounting one of the tricool fans from my old 900 on this new case.

Absolutely love the case, the design is elegant and stylish, I didn't want an eyepopping design, something cool and simple, yet something about it says it's hiding a few secrets under the hood :)
