I added another few mm to the case height, but this time I also tried out what it might look like to have the case be as small as possible while still fitting common DC-DC components. This is what I came up with. The length and height are nearly square now, with dimensions of 199mm x 198mm x 105mm.
And a rear view of the case (which is the first time I've shown it BTW):
The back panel design shows no visible screws, and the card is installed by removing the top side. The power inlet is still a work in progress.
The GPU has been moved about 15mm down to support taller cards in this setup. While this means you probably can't fit HD-PLEX AC-DC power units anymore, the DC boards that are 2 inches wide fit with room to spare. This would be a great setup for builds if you don't mind using an external power brick, or some with internal PSUs for lower power builds.
That is not to say I've ditched the idea of 400W brick-less builds with all the components inside. This smaller design is more of a side step, which can branch out to a second, somewhat larger case that can fit cards as long as the Zotac 1080 mini.
So if I am to make two different cases based on similar designs, I still want them to be different enough in features to support more uses for the larger one.
