@sergiiua quick question:
1) do you have plan for a 3slot gpu sfx case (or a 2 slot one that accept gpu up to 53mm in thickness **the 1080 strix** ) so were able to close the side pannel with those cards
2)can you adjust the gpu length informations on the first page for the different configuration? because im guessing that I can go with a strix only if the power button is on the back (its about 3-4 cm longer than the 278mm written in the description) only if thhe power button is on the back
3) is there flex in the honeycomb design side pannels?
You can have him make a custom case for you that fits those specifications, as I recently did, just make sure to specify where you want the extra width to go as I did (i.e. total width 150mm, add 20 to motherboard side and 10 to GPU side).
