In the spirit of "your setup, should be your setup. As traditional or as custom as you’d like!" as mentioned in article, I went with a vertical mount rack. It's not enclosed so it has enough ventilation.

The advantage with a vertical rack for me was space savings. Key parts of my home lab are near the low voltage panel (lucky to have in newer house) which does have foot traffic from other household members. Much less risk of someone bumping into the rack.
