I honestly haven’t gone under the hood yet, but I’d imagine that it’s a pretty tight fit in there. I do believe that the entire back panel can be removed, so that should at least help with accessibility.

Yes, you can get the OMNI with 32GB of RAM. I purchased one last month, and so far have been very satisfied with it; pretty much everything in Mike’s review is spot-on. Overall, it’s a sleek, solid (yet pricey) piece of tech.
