I now have 3 Pelican cases and plan on buying even more in the future. I bought the Pelican 1500 Case at the same time as the 1650 and have owned the Pelican Air 1535 for about 4 months now. I run a small video production company, and use these cases for storing and transporting almost all of my equipment, from camera bodies and lenses to microphones, monitors, and even a slate. The 1650 is a very large case, and held a large amount of equipment for me. As far as ''constructing'' the inside of the case with the pick-n-pluck foam, I took some advice from others on the web and used toothpicks to mark out the sizes of equipment before doing any actually plucking and picking. One of the best decisions I've made with this case was ordering the Pelican 1659 Lid Organizer at the same time. I haven't installed lid organizers in the 1535 or 1500 yet, but after realizing how convenient it is to be able to throw my spare camera batteries, cords, and other miscellaneous pieces into the lid organizer (instead of a separate bag or backpack), it's something I plan on looking into. Anyone who has experience any Pelican case can speak for how stellar the build quality is. These cases are clearly built to last and I never worry about storing several thousand dollars' worth of equipment in mine, especially when they can also be locked up. These cases are incredibly sturdy and built to make transportation easier, and the 1650 is no exception. It has two sets of double wheels on the bottom edge of the case as well as an extending handle that allows you to roll the case with ease - a definite need for this case since it's far too big and heavy to lift and carry anywhere. This case is deep enough that it actually has 2 rows of pick-n-pluck foam instead of 1 row (which the 1535 and 1500 both have). I was able to take advantage of this depth with a few items, most notably the suction mount, slate, and rail system. I've attached a picture to my review in order to get a better reference for just how big this case is and how much it can hold, and I'll break down the equipment inside now for those curious:-Canon EOS 70D Digital SLR Camera-Canon EOS Rebel T3i Digital SLR Camera Body-Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens-Rokinon CV85M-C 85mm t/1. 5 Lens-Blackmagic Pocket Cinema Camera-Aputure 7-Inch Digital Video LCD Monitor-Matte Box-LP-E8 Battery Chargers (2)-Suction Cup Mount-1/4'' Mount Stand Thing-Hot Shoe Stand (x2)-AA/AAA Plastic Battery Storage Case/Organizer/Holder-Clapboard with Color Sticks (9x11 inches)-160 LED CN-160 Video Light (x2)-Opteka Follow Focus-Opteka 15mm Rod SystemI was able to fit a ton of stuff in the lid organizer as well, mostly extra batteries, a power strip, a sunshade for the monitor, pens/dry erase markers, gaffer's tape, cords, etc.
