And finaly here it is all complete! Sorry I didnt explain everything step-by-step. It would have taken WAY too long. And just to let you know, I have all the fans blowing in except one of them on the top is blowing out, and here is also an open back to it.
And also I used 2 coats of Minwax water based stain, and 2 coats of polyacrylic on the outside. As well as siliconed all the inside edges or gaps to protect the unpainted wood.
Thanks for taking a look. I will update this in a week or so, after I get all my LR and water setup.
