Sonnet Breakaway Box Review - It's cool to be quiet
The fans are off when the enclosure is not connected to any host.
can I install a liquid cooled GPU in it?
Yes you can
But not in 350W version. Liquid cooled GPU assumes high power consumption. You can, however, easily upgrade the power supply to much higher power - just need to make sure it is SFX format
I suggest waiting a bit longer for Vega RX (or whatever it will be called). Frontier was never meant for eGPU use; even though it does fit, it will require power supply change.
Sonnet has published a comprehensive list of compatible graphics cards at http://www.sonnettech.com/product/egfx-breakaway-box.html?tab=2
I am thinking of getting one of these but I need to figure out how to squeeze it into a crowded edit workspace. How hot can the exterior of the case get when under heavy use?
As long as the airflow is not blocked/restricted the case is barely warm to the touch.
I'd be interested in a version without a PSU, as I'd rather replace it with a Corsair fully-modular SF600, which looks like it would fit.
