And I will post in here as well (please note, I'm not singling anyone out or lambasting anyone, just explaining what the actual issue is)
The Aquaero units most people are having issues with are the Aquaero 6 (Pro AND XT models). The problem doesn't lie with CaseLabs, all of our chassis are designed to meet international specifications. The problem is with the Aquaero unit's mounting brackets (or arms, if you will) for 5.25 bays. It seems that there are 1 of 3 issues with the units:
1. The holes for mounting the entire unit together on the mounting brackets using the front screws on the Aquaero were not drilled to allow any kind of wiggle room side to side, meaning they can only be mounted to the unit.
2. The mounting brackets themselves are too large in material to allow proper mounting in the 5.25 bay.
3. The mounting brackets were drilled too far out from the unit.
ALL of these reasons come down to the simple fact; the Aquaero does not want to fit in 5.25 bays (this includes my Lian Li as well, so it's not an issue with CL).
The reason why CaseLabs has developed the non-conforming shim brackets is for this reason, to allow the user to install the Aquaero and have it fit seamlessly. Users who've bought the adapters say they work wonders and allow the A6 to fit perfectly. These will also work if you have any other device that doesn't want to play well with 5.25 bays (Disc Drives, fan controllers.... cigarette lighters.... etc). Since MANY of our customers opt for the Aquaero controllers, why not fix the issue ASAP instead of waiting for it to be fixed?
