Looks alright for a LAN.
Although space is often an issue, so I'm not really sure it's the most appropriate case for a LAN - definitely not above the Prodigy, and it's not like you need a full ATX sized case to max out games anymore.
For a test bench, I don't really see it being accessible enough tbh.
Then cooling wise, I don't see it being better than conventional cases.
I just see it as something different really. Maybe a final attempt at CM pushing the HAF design as far as they can - despite it being pretty exhausted by now.
I'm not a massive fan really - Just don't see the point, and feel it would take up too much desk/floor space for my liking.
