    The heatsink visible if for the 5V section. It is too small and gets really hot. When the case is mounted, the heatsink touches the case and so, heat is convected to the case rather effectively.

Re: PSU section

Just realized, the heatsink is for both positive regulators, +12V and +5V. Thats why there are two screws…

Re: VFC section

WOW!!!

Great! :thumbsup:

Any problems with background noise?

Re: VFC section

No noise at all in the audio path, but the transformers are buzzing faintly. I can hear it if I put my ear close to the case.

Re: VFC section

It’s looking lovely! Wonder when I’ll have time to make mine? Guess I have to retire first…

Re: The interior

Kick ass! I would have figured 2U just to be safe. This is a wonder of compactness :sorcerer:
