Looks nice mate. Did you put feet underneath as well or did simply raising the top make it the correct height? How tall are you?
nope no feet underneath only the extra shelf on top, im 5โ9" and the capita legs raised it the perfect height for me and the right size to get a amplifer under there aswell! 
looks like you did what I did. If you want add a shelf over the whole set up and move the leds under it. THen the gear is lit up, plus you have somewhere to put your laptop.
