The guts don't matter.
If you ever saw the inside of MY cab, YOU'D probably laugh.
I've got wires going EVERYWHERE in there.
Fortunately, most of my wiring is done with Cat-5 cables, so it's all mostly bundled.
Your cab looks great.
The one thing I noticed about it though is that the monitor bezel seems to stick up above the table top.
Are you planning to add cocktail glass over the top?
If so, you may need to rout the monitor bezel into the top, to get the glass to sit flush.
