Pros: Great way to add an intake fan to help get positive pressure in some cases. Looks fine. Has a low noise fan.

Cons: Shoddy assembly. The dust filter in mine was not installed flat and the fan rubbed across it, soundling like a baseball card in bicycle spokes. Had to disassemble it to flatten the filter. Which was fine, because I replaced the fan. Sleeve bearings are quiet, but don't last very long. I stuck in an s-flex with the same RPM, but with FDB bearings. And you better get used to disassembling it if you want to take the filter out for cleaning D:

Overall Review: bottom line: good way to get in another fan without a dremel.

Pros: Great case component in place of unused drive bays, to: direct cool air at your CPU heatsink, memory sticks, and/or toward your power supply. This can also be mounted horizontally for use as a CD/DVD drive cooler or hard drive cooler. Can be mounted behind drive bay covers or mounted flush with your case's front if you remove the drive bay covers completely. I LOVE the way this baby channels air at a perfect path from the front of my case through the CPU heatsink of my AMD 64 X2 5200+ and directly out the back of my case / up into and out of my power supply.

Cons: The stock fan it comes with is a nuisance. Poor RPM. I removed it with a screwdriver to replace it with a quieter Scythe fan that runs up to 1200 RPM. I've got a XION Solaris case (newegg reference: XION Solaris XON-403 Black with Green LED Light Steel ATX Mid Tower) in which this bay doesn't fit as snuggly with the front left side as it does with the front right side of my case.

Overall Review: This drive bay matches my black/green XION Solaris case in both style and color perfectly. Despite the slight asthetic imperfection of a not-so-snug fit that creates a slight, visible gap between the fan bay frame itself and the left side of the drive bay spaces, it does fit flush with the front of the silver accentuated side paneling that front face my case. The 4 screws on each side hold it securely in place within the empty drive bays.

Pros: The only fan that fits into drive bays that I could find on newegg. Nice piggy back power plug

Cons: Although it comes with a filter you have to disassemble fan to take it out to clean.

Pros: Silent fan, great mounting system.

Cons: Fan doesn't push too much air.

Overall Review: The "steel frame" mentioned by the other reviewer is actually aluminum. It's made so you can mount the fan in a CD-ROM bay either to blow air vertically, or you can mount the fan to blow air horizontially. I purchased this to bring some more air into my CoolerMaster Centurion 5 case and have been very pleased. I ditched the fan for a faster one with blue LEDs.

Pros: Pros - moves a lot of air - incredibly quiet, thought it wasn't on - comes with a filter - mount is very sturdy and well built - the mesh is very nice - comes with 3-pin mobo hook up, but 4-pin molex adapter is included - any 120mm fan could easily be swapped in

Cons: Cons - installation makes regular filter removal difficult

Overall Review: If you have three empty 5.25" drive bays empty up front then this a wonderful addition to an air cooled setup. It lowered my temps 1*C at idle and 2*C at full use.

Pros: Fits perfectly in 3, 5.25 drive bays. Was just what I needed to add an additional 120mm fan to the front of my case.

Cons: None

Pros: It actually works! (with a better fan) pulls in air right onto my CPU and dropped temps by 3-5 C

Cons: took me 35mins to get this thing in my case. its a B$%#@ and a half to mount. first of all i have a toolless case so there are no holes to mount the screws (that are too small for any hole) then i tried mounting it with my drive rails and that works tho it is still a bit wobbly and there is a 1/4 inch crack on the left and right side where i can see right in the case. and finally the fan is junk (only 800 rpm) replaced it with a zalman 120mm green LED fan (looks cool)

Overall Review: a good idea but only if its gonna 1) line up with case holes 2) comes with a decent fan and 3) if it was the same size as 3 drive bays

Pros: It's only $20, and adds extra air flow towards my ram. WAS quiet...see cons below.

Cons: Some what flimsy construction, although for $20 including fan it's good enough. Also I have gaps on both sides(just slightly to small for the opening)...it almost looks as if it's out of square too. My only real complaint is after 1 month of use the fan would occasionally start marking noise. Now after 6 months the fan emits a constant clicking sound, although it's still currently running.

Overall Review: Maybe I received a defective unit, but I expected the fan to be higher quality...being Scythe branded. I'll probably have to wind up replacing the fan. Still, before these things came out last year I was planning to buy some modders mesh and create something just like this. For $20 this saved me a lot of time, and accomplished the same goal. For quality issues I gave it 3 stars, but I'd still buy it again.
