Pros: Fans seem really quiet. I love the look of these in my red/black themed rig. (I'm revamping my older pre-RGB build lol). They look great with leds on, and with the system off. The 4 pin connectors and cables are sleek black, plenty of length. Some other reviews mention that the LEDs are "dull". I wanted fans that weren't overbearing with the amount of LED lights and excessive brightness, so these are perfect for me. They certainly don't look dull to me. I'm going to order more soon.

Cons: Not worth taking an egg, but another reviewer mentioned big white barcode stickers on the fans that leave residue. I found a easy cleanup trick. Regular scotch tape pulled up the barcode sticker residue with ease.

Overall Review: Do it.

Pros: Just put together a new build with this MOBO, 16GB G-Skill RAM, Samsung SSD, and the 3930k CPU. Using this build for music production and it works great. Not a single issue yet.

Cons: Haven't had any issues.

Pros: What a great unit. The routing options on this are endless. Incredibly versitle. Sounds AMAZING. Have used it for tracking guitars and bass in the studio and it has proven itself. Edit software is a must. Looks sexy in my rack.

Cons: The built in screen/GUI is a bit archaic. The edit software is a must for anyone who wants to customize the deep parameters.

Overall Review: I use one in my professional recording studio. My guitar player uses the HD500 pedal live. Just get one!
