Summary: Overall this is a good, solid case...though I expect no less from Antec. I have two builds with their 900 case(my favorite) but when with this one for my wife's system due to the cat sitting on top of her case. The power buttons and usb connectivity on top of the 900 wouldn't have been good in case the cat accidentally stepped on one of them.
Summary: The case is really great for the price, but... This is the first Antec case I have purchased that wasn't five stars and that is because the extra brass standoffs supplied in the zip lock bag were actually too small on the diameter of the threads. Couldn't tighten, just spun! Boy was I hot! The standoffs in the plate for the motherboard, when moved around, securely fit the pre-drilled & tapped holes.
Summary: Large case, nice layout, but still with quality flaws. As many pointed out, the off-sets for mounting the motherboard are not worth much, as there are no threaded inserts for them, they are just screwed into the thin sheet metal - and WILL rotate even if you are very careful. Luckily I had some captive nuts so I could save the day after all, but a few holes were missing for properly mounting a GigaByte ATX motherboard.
Summary: We're building two computers, one for myself, and one for my son. I've had Antec cases in the past, and have been very happy with them. This case is no exception. It has plenty of room, and a good cable management area behind the motherboard. The only thing I would have liked to see, is a thin rubber seal over the cable management holes. They don't need to be the grommets, but at least something to cover the sharp edge of the metal.
Summary: Aside from having to drill a new mounting bracket into the case for my board this was everything I was looking for and fit all the parts without issue. There is a mounting fixture to attach a fans to the side panels which I may not ever take advantage of, but cooling seems to do well enough just from having the mesh in those sections. Antec served me well in the past and I'm happy to say it's working great again.
Summary: This is my third Antec case. I have a 900 I got 5 years ago and still love. I bought a 300 for my brother 4 years ago and liked it. I needed a solid case for a HTPC in the bedroom and wanted good cooling and quiet operation.... Well as quiet as possible. The 300 has been very well upgraded from what I used 4 years ago. I like this a lot! *Great cable management. The drives slid in sideways and are tool free.
Summary: This is a quality case. Very large with a lot of wasted space because of the design. Pros: Very sturdy with easy 3.5 HD installation. 5.25 Optical bays are just push in and your done. Plenty of room in back for wiring management. Fans are almost silent. I don't overclock so I leave them on low setting. Doors slide off easily as well as the front bezel. Cons: Don't get this case hoping for SSD dedicated mounting points in this case.
Summary: Nice solid case. Plenty of room. Cables can be hidden behind the mother board. Easy to access hard drives. Power button seems flimsy and is easy to accidently press with your leg. Antec stands behind its products so one call and the will probably take care of any issues that arise.
