As long as you're aware of the limitations (and perhaps have an external USB hub? ) that sounds good. Just something to be aware of - even many angled connectors protrude more than 18mm from the socket

It might not be a lot, but it might also be a noticeable amount - it's really rather impossible to tell until it's been tested. Not only is guesstimating airflow really complicated in and of itself, but judging just how restrictive a layout is by eye is next to impossible too. I've seen some layouts work that seemed like they would choke entirely, and I've seen some ones that seemed well ventilated end up with very poor thermals. Airflow is a finicky thing. I would recommend testing as much as you can before committing to ordering any sheet metal, as changes after that can become expensive!

Heh, there are enough of us here using industrial 12V PSUs that I don't find it that crazy (many of those are open-frame to begin with), but given that it requires soldering both AC and DC power wiring it's a bit sketchy still. It can no doubt be done though, and while the space savings aren't huge, it's the design oppurtunities spawned by this that really matter

[QUOTE="Valantar, post: 257452, member: 5738"] As long as you're aware of the limitations (and perhaps have an external USB hub? :P ) that sounds good. Just something to be aware of - even many angled connectors protrude more than 18mm from the socket :) It might not be a lot, but it might also be a noticeable amount - it's really rather impossible to tell until it's been tested. Not only is guesstimating airflow really complicated in and of itself, but judging just how restrictive a layout is by eye is next to impossible too. I've seen some layouts work that seemed like they would choke entirely, and I've seen some ones that seemed well ventilated end up with very poor thermals. Airflow is a finicky thing.

Heh, there are enough of us here using industrial 12V PSUs that I don't find it [I]that[/I] crazy (many of those are open-frame to begin with), but given that it requires soldering both AC and DC power wiring it's a bit sketchy still.
