In general, no matter what your glue question is, my glue answer is epoxy. HDPE is almost as difficult to glue as UHMW or Teflon. Very low surface energy. I'd recommend cleaning with isopropyl alcohol to remove every trace of oil from the surfaces (HPDE and panel), allow it to air dry, and then use a liberal amount of RTV silicone. You seemed to be heading in that direction with your Goop musings. Don't be stingy. Slop it up the sides of the HDPE if possible so it has more surface to grip and it's protected from shear loads, which are the enemy of adhesives.
I've had good luck mounting stuff like PC power supplies and solid state hard drives inside a panel with 3M VHB double sided tape. VHB = Very High Bond. It's the stuff the auto industry uses to attach automotive trim strips to prevent automated car washes from yanking them off. Even then, I try to mount these components on the base of the cabinet so gravity is helping the adhesive bond rather than trying to peel the device off the vertical side of the panel. I use powder coated steel cabinets, and that's a slick surface that doesn't bond well. Even worse, it's a crinkle finish so there's about half the surface area or less for the adhesive bond to grab.
