Hey thanks for bringing that up. I'll have to do a couple checks to see if I can mess with the layout a bit more. It may be that you need a dynamo kit to use the hdplex 400 and a reference length gpu, and a 210 length with the hdplex 400 Ac-dc. It is also possible to move the psu, since the hdplex is only 60mm in width, and it'll fit with the hdplex 400 dcatx behind it.
Note, I plan on finalizing a 400W itx psu platform soon, targeting to replace with this unit.
Will the PSU be seperate? I saw a video by Josh of him unpacking the Pure, and it seemed to come with the power button and Mean Well RPS-200-12 along with a bunch of other custom length cables for it. Is this case going to be like that? I really liked the custom cabling and the way that little Mean Well looked in the Pure, i think I'd prefer to just have a Mean Well and some custom cables bundled with this case.
