I could not wait to get it inside and start playing. 

With some help, I moved it from the garage into the house.  I rolled it into the middle of a room.  This is where I installed the T-molding.  Since it is such an easy process (actually, I forgot) I did not take any pictures.  Just force the molding into the grooves you cut at the start and smooth it all down.  A rubber mallet helps and I used the side of a screwdriver handle to smooth it all down.  At some of the corners, I was forced to cut a 'V' of the molding groove out so it would lie flat.  I used a steak knife but anything sharp will do.

Once that was complete, I moved it to the room where it would be set up temporarily.  Then I loaded all the components inside and powered it all up for a nice test drive.

Take a few pictures so your co-workers can be jealous and start playing.  I actually used it this way for most of a week before continuing.  Whenever you are ready to continue, move to the next section.

Update- 5/26/07- To answer a popular question, I placed T-molding into the backside and front side of the X-arcade slot, not the underside.  This will make a very snug fit for the controller, and at the same time protects the controller itself. See bottom-most picture at right.
