Glued and screwed together. Trim pieces were glued and attached with a brad nailer. The doors (front and both sides) have European hinges, or will have, I'm still waiting on the correct hinges to be delivered. The side doors open wide enough to slide the sump in and out.
No build thread yet, maybe I should start one or two or three. Major renovations happening in the basement for a 850 sq ft man cave with a 180 mixed reef in wall with a fish room behind it. The stand above is for a 60 gallon cube going in my office. It came with a stand but it has some water damaged particle board and I don't want to put 600+ lbs on top of that.
Here's some pic of the construction of the stand...
