People have, I'm waiting on my 545lc and will post pics when I get it of it all installed and set up.
In response to the above request for a 240mm pedestal, I myself would love a 30mm thick extension to the bottom of my Dan for airflow and better cooling for the radiator. I'm wondering if I could make something that only requires connecting the fans, almost like a cooling base for the case.
Maybe further to that, I reckon a desk with a build in 184mm cooling plate would be pretty neat
Edit: you know what I just thought of, what about a Louqe Ghost S1 top hat as a DanCase pedestal? You can buy the top hats and grill separately to the case, which would allow you to potentially and quite stylishly add an external radiator via the enclosure and maybe some larger openings in the bottom of the A4.
In my use of a medium tophat with 2 120mm Redux fans, I could plug in the pedestal at home for additional airflow and cooling, then unplug it for lans. Would cost about $110 including shipping after my kickstarter discount... Hmmmm
