I bought a KSD, FT Hana mini clone (Hotcig) and 6 Cloupor enclosures (warranty returns). 4 of the Cloupors didn't work for various reasons (burnt boards mostly) and 2 worked but woke from sleep by itself a few times a day but otherwise worked fine. The only one I left alone was a red Cloupor. I moved one working Cloupor board with a display issue to the KSD and the Hotcig board to one of the Cloupor boxes. I have DNA40's in 2 Cloupor boxes (1 lg screen in a blue box, 1 sm screen in an orange box) and a lg screen in the Hana mini. All but the red has VT 510 connectors. I sold 2 basically for the cost of shipping to a member here because he had no luck getting them from Elev8 (they sell out really quick).
I think the Cloupor boxes are much nicer than the KSD boxes. The side edges are more rounded so they're more comfortable to hold. The finish is also nicer on the Cloupors.
They all ground to the case with a screw from the top except for the KSD. You should be able to find the ground screw at any hardware store.
