  1. SM5.. Perfect

    Posted by Justin aka MocoIMO on 1st Oct 2014

    To start off my only personal issue is wanting the window a bit larger so I could view my res after all the time/money I've invested because the Gunmetal + extra UV fluid shining would be even more epic(again for me).

    The build quality on this case is AMAZING. I easily modded the backside so I could mount 4 HDD instead of 2, + holes for my res on the main chamber with no issues. Highly recommend for a spacious mATX WC setup.

  2. Solid build

    Very sturdy case, NO PLASTIC!

  3. This thing is awesome

    Got this for my gaming rig, theres so much space inside, the hard drive placement is pure genius, I love how you can chose if you want 5.25" drive bays or not, cooling options are almost limitless.

    The flexibility and build quality of this case is just amazing well worth the money.

  4. SM5
