Cheech:
My design is much closer to your first. I wanted more room for the sump and fuge and then the side cabinet for all my electronics. I wanted to add a fan/vent to keep the ballast for the MH cooler and to mitigate any (though small) impact to evap. I personally like the first design but would consolidate the two end pieces to one to maximize the cabinet space. I realize that design wise it is then out of balance, but I am a function person. IMHO.
And thank you very much for the kind offer!
