I just finished my build of my stereo integrity HT18-v3's for my home so figured I'd share to give some inspiration to others.
Edited to fix picture rotations

Flat Packs arrived
Laying out all of the pieces
Starting to glue them together
Getting SVS feet ready. They use the 1/4-20 tnuts as well.
More gluing
Sides being glued on
Silicone all of the seams to make sure no air leaks. Also siliconed the tnuts since the svs feet bolts were not long enough to go all the way through
Silicone Dry
I recessed some magnets in the front face on the backside in case I want to add magnetic grills in the future. I wish I would have purchased some stronger magnets for this. These are fairly weak and will require a much stronger magnet on the grill side to work properly.
Magnets epoxied in place.
I may have issues with excessive clamping...
Boxes all glued together
