4 out of 5 eggsLow Cost

Pros: Nice price for a back-up computer build. Plenty of space inside for cables and a large video board. You have plenty of slots for moving the internal 3.5" drives around to clear video boards. I was happy to see the front panel connectors were long enough to go behind the panel that the motherboard mounts on and come out lower with enough cable to reach the headers.

Cons: No manual - There is a half page diagram with features. When you go to the web site you find there is no PDF manual for this case. I downloaded other manuals with similar configurations and used them (NSK3480, NSK4482).

Other Thoughts: Box was damaged and back of the right side panel had a ding and paint was flaked off. I don't know if this was a shipping, warehousing, or manufacture problem.

5 out of 5 eggsGreat Case

Pros: I like the style and it does what it's supposed to. I had no issues putting it together. Nice lightweight case with enough room for all my components. Metal is thin, but it gets the job done at low cost... I'm satisfied with my purchase.

Cons: None that I could find.

Other Thoughts: I think it's a good inexpensive case.

3 out of 5 eggsDecent cheap case

Pros: Cheap. Looks nice. I like power supply top mounting - not at the bottom.

Cons: My only complaint is that the front panel fan mount holes are actually small threaded holes the same size as motherboard mounting screws instead of the standard wider holes that accommodate the normal fan mounting screw that bites into the fan frame. Case did not include screws that would work.

Other Thoughts: Even in my mondo bag of spare computer screws I don't have a screw long enough to pass through the fan frame and into the case. Haven't a clue why they'd do it that way since fan mounting has been standardized for a very long time. So I'm without a front panel fan until I find the right sized screws.

Rear fan mounting is the normal kind. Go figure.

2 out of 5 eggsLooks good

Pros: Front looks good. Placement of the I/O ports and buttons at top is nice. Looks like it could be a decent plain business PC case (which is why we bought it).

Cons: My biggest problem is Antec marketing describing this as "sturdy SGCC steel". While the finish looks nice the steel is thin and the frame is weak. When standing up right it doesn't sit flat, and instead rocks back and forth to the sides. The frame will distort and bend easily just by picking it up with your equipment mounted inside. Clearly these are constructed poorly given the few loose pop rivets at the corners. You will REALLY notice how flimsy this case is when you try to bend out and remove the expansion slots for a graphics card.

Best way to describe it is cheap. I can understand the lack of thumb screws, no 2nd fan in the front, or an easy way to mount disks or drives, all to save a little money. But with this case you can literally see the places they tried to cut costs. It's evident even with the thin, flimsy box in which it shipped.

Other Thoughts: Here at our office we build our own business desktop CAD machines and unfortunately we are having a hard time finding a case that doesn't have all kinds of enthusiast features like neon lights and water cooling ports. Not sure why it's so difficult for these manufacturers to build plain business cases anymore that aren't so cheap they bend when you pick them up.

Bottom line, this is maybe a $40 case (I am being generous because the front looks good) so if you pay more than that you are wasting money.

5 out of 5 eggsUPGRADED TO A '5' STAR

Pros: Exceptional design for the money. All the great features of a high-end case in a small, attractive form factor. Good ventilation with plenty of fan options (no fans in top of case though). I bought it for a Hackintosh build.

Cons: None for everyday use. I am overclocking a SB 2500k @ 4.4 ghz using only air to cool it with and am having no heat issues whatsoever. I did install a large fan on the front of the case to pull in cold air up from the bottom. Not for extreme overclocking, but standard o/c does very well.

Other Thoughts: I gave this case two bad ratings. After changing the motherboard settings, I discovered a pcie setting was disabling USB 3.0 from the motherboard, so it was NOT a defective USB panel on the Antec case.

Sorry for the bad ratings, Antec. You have produced a fine case here anyone would be pleased to use.

1 out of 5 eggsDowngraded to a 1 star

Pros: Kept this in the case for over a month. Now it is not eligible for an RMA, so the case is worthless without the front USB panel working.

Cons: Front USB panel USB ports do not work.

Other Thoughts: Have to buy another case which will add up to well over $100. Could have bought a premium case for this price!

Manufacturer Response:

Hi PCGuy,

We apologize for the defective front ports included in the case, we'll gladly replace it with a new one. There's no need to RMA the whole case. Please contact our customer support at 1-800-222-6832 Monday through Friday, 9:00am to 4:30pm Pacific Standard Time or online at

Thank you,

Antec Support Team

2 out of 5 eggsBAD USB PANEL

Pros: Great layout, good airflow, good design, attractive.

Cons: USB PANEL did not work most of the time in USB 2, none in USB 3. Installed using a known good motherboard, the case's USB connector was defective. The USB cable is a 'dual USB' connector with one 2.0 and one 3.0 connecter on the same cable.

Other Thoughts: This should have been a five star rating, but the bad USB Panel brought it down to a '2'

Hope Antec will make this right and send me another USB panel for this otherwise great case.
