Yeah, the LA fits fine in my entertainment center, almost perfectly actually with a couple of PACs to the side. I think I took a picture of the setup in the happy place thread and posted it there.
Personally I think the composite is okay for what it is (much better than a stock Genesis for sure), and all things considered the RGB mod is pretty easy to do.
I understand what you're saying about it being unwieldy to some folks Black Tiger, but personally I found it to work very well for my gaming setup. Now, this is also considering the fact that I didn't have to pay $1600 or more for my unit like you would have had to do when it was new.
