5 out of 5 eggsGreat Case

Pros: I've used this case for a few builds over the past several years. The builds always go well. Motherboard and standoffs always line up, backplate lines up wall, drives and power supplies fit nicely, no sharp edges, cables to the front panel (power/reset switch, LEDs, USB) labeled and long enough. It's easy to remove drive covers. There's a convenient channel beside the drives to run cables. Lots of options for fans. The fans that come with the case are quiet and seem to last quite a while. Enough space for most large heatsinks and video cards.

Cons: None

Other Thoughts: Apparently there's an upgraded version. Not sure what the difference is, but this "old" version still works great for me.

5 out of 5 eggsGreat case!

Pros: This case is wonderful! The larger size and bottom mounted power supply bay made it very easy for me to mount a lot of hardware (mobo w/ large heatsink, radeon hd twin fan graphics card, and 3 hard drives). I removed one fan and don't use the other fan, and everything is still running 10 degrees C cooler than in the case this one replaced.

Cons: None.

Other Thoughts: I bought this to replace a case that had a weird humming (probably due to some resonance caused by the cofiguration of devices and hardware) and didn't feel like playing games with loosening screws (Yikes!) or adding sound insulation to already toasty case.

5 out of 5 eggsTerrific Mid Tower Case

Pros: You will not find a better case for the money. HD construction, lot's of room. Makes for easy builds. This is the older version, I now have built 5 units with this model. Excellent cooling options. Did I say cheap $. Now that they are closing them out, you can can get them for under $35 after rebate. And free shipping. Great deal, great case.

Cons: This older model doesn't have front USB 3.0 ports, just USB 2.0. If that is a deal breaker, then get the newer version with USB 3.0 ports.

Doesn't have much cool factor to it's style, but very functional.

Other Thoughts: Antec makes great cases, and this has been a favorite for a few years.

5 out of 5 eggsPerfect for small form factor performance

Pros: -Client wanted this computer case. I was a bit skeptical since I usually pick the biggest case possible for the money, but was pleasantly surprised that it ended up being easy to work with.
-Fits an HD 6970 with some room to spare
-Simple and clean look that means business, not play time.

Cons: -None. For the money this is a bargain.

Other Thoughts: Recently built another computer using a huge HAF 932. This build didn't feel any harder.

5 out of 5 eggsAs always

Pros: Perfect price/performance case in it's day. plenty of fan options, and understated elegance.

Cons: None really. See other thoughts.

Other Thoughts: If any one is reading this you probably don't want this case now. There is an updated 300 that has 3.0 USB ports and better SSD mounting options. I own three of these and the only reason I bought this is was to move an old rig into a new case. There is no real reason to buy this case for a new build.

5 out of 5 eggsAntec always a good case

Pros: Building a rig for a customer's automation system and needed a decent looking black case. Plenty of room for a standard ATX form factor MB. SSD mounting on the floor of the case is nice as well. Runs quiet on antec's fans. No complaints whatsoever.

Cons: None.
