What type of case is that cube? It's not from Yeong-Yang, not the YY-0221 nor the YY-04x0.
Its from the US, Mountain Mods Extended Ascension. $1000 au shipped to Australia, so not the cheapest case around. But it was the only case that would fit everything. I used to have this setup below with 2 cases with an externally connected water loop between them. Left one for computer and right one dedicated cooling case.
I had a baby coming so I had to consolidate everything down to a smaller space and keep it tidy as its now in sitting in the front dinning room as apposed to dedicated 'office'.
