    Great for fro t ventaliation

  2. Excellent quality, one small design quirk

    First, let me say how impressed (as always) I was with the precision, materials, figment, & finish. In addition, the included screws were great and CaseLabs includes plenty. My one nit-pick is in regards to the half-circular cutouts at both ends when it comes to radiator end tank ports. They MOSTLY line up with AlphaCool radiators but pretty much no other models on the market, and they aren't "deep" enough - I had to file approximately 10mm more in toward the center on one end to even install the 420 (140x3) radiator INSIDE the bracket. Not a huge deal but if the design had been made where the material was simply cut straight across much lower it would still be plenty strong (have enough material width to provide stiffness and support its own weight and that of the radiator + fluid + fans, and I wouldn't have had to modify it.

    Couldn't ask for more. Mounted 3 fans to the front of my SMA8 with it.

  5. much better than 120x4...

    Posted by ak on 28th Jul 2014

    i have both 120x4 and recently 140x3, but the new 140x3 mounts have cut outs on both ends for more fitting on the opposite end which makes it more handy (good for drains), less space (12bays vs 11bays)and more cooling power.

    140x3 has more surface area.

    note: both mounts fit up to 38mm FAT fan on the front, will need flat screws to mount the front grill back.
