Ok, I've managed to make some time to work on the new cabinet. With the exception of the metal flakes on all around (from drilling), everything seems to be going pretty good. I picked up some elbow vents, eye hooks, a dryer vent, and a desk wire cover.

So far, I've drilled two 4-1/8" holes - one in the top of the cabinet, and one in the top shelf. I've also drilled one 2-3/8" hole in the top shelf. In addition to those major holes, I've drilled about ten other holes for screws and bolts to hold up equipment.

I need to go back to the hardware store and pick up two more duct clamps and one more desk wire cover. Once I have those, I'll need to drill one more 2-3/8" hole in the top right of the back of the cabinet, to allow the power cable to exit the cabinet. I need the clamps for the venting from the elbow on the bottom of the shelf, to the filter. I also need to install four more eye hooks. These will support the main light, and the T5, when I hang it vertically, for side coverage during flowering.

I will need to line the bottom portion with mylar. This will help to close up the shelf bracket holes, which could let in light during my 'night' hours. I will also need to cut a hole in the bottom of the cabinet for an air intake vent. I picked up some filter material, which I am hoping will minimize the light coming in from this vent. I will place the filter material between the vent cover and the cabinet. It will be stored in a utility room, so I'm not too worried about light getting into the room.

I've attached some photos of the work completed so far. The first is the dryer vent on the top of the cabinet. It was a little tight to get into the hole I drilled, but with some coercion, I managed to get it in the hole. The second is the cabinet closed. The third is the cabinet open. And the fourth is a close up of the equipment I installed so far. Unfortunately, the vent is covering up the desk wire cover, I used for the power from the ballast to the light. I'll probably need to tape that up, after all my cables are in place, to minimize the light.
