Hi there!
I don't have much information about this case but from what i understand you can't buy it anymore. I love the layout and i want to ask, is the old version (L4) compatibile with HD plex 160W AC-DC psu, for a brickless build?
Actually, for brickless using HDPlex 160w ACDC, the answer is more like no.
Here is a response within this thread with an image, which shows HDPlex 160W ACDC won't fit with HDPlex's DC-ATX Unit:

If you don't plan to add any graphics card, I believe the ACDC unit can go to where the graphics card would've gone. But then, that comes with the question of why get a case with dual low profile slots, if they are not to be used.
There are also some comments about it around here: https://smallformfactor.net/forum/threads/lone-industries-l4.901/page-25#post-93151
But a creative use of PSU, like this one, using Meanwell PSU, this looks brickless: https://smallformfactor.net/forum/threads/lone-industries-l4.901/page-21#post-59534
Remember that L4 is a compact case, and placing ACDC PSU inside the case would result in even more heat into the small space.
