hey, how is the search going? I just did my custom cage this weekend!!! I couldn't be happier with how it came out!!! I built it out of melamine shelving from lowes. i was going to make a flip top too, but decided on sliding plexiglass doers in the front. It came out great!!! If you are interested, I could totally help you along the way. I did a ton of research before I started and it was well worth it. let me know if you want help… My dimensions are 36 wide, 16 deep and 18 tall.
