content: I have an idea for use of a Raspberry Pi 2, but it's dependent on being able to get the HDMI output socket on the same plane as the USB and LAN connectors so they can all be exposed on the back panel of the case.The first idea I can think of is a short HDMI extension, but there are 2 problems with that. Firstly, even the shortest cables I can find are way too long, and secondly, I've not been able to find any extension cables where the socket is panel mounted.In this project the Pi would be mounted upside down on a larger carrier PCB (which would have all the other electronics I need) via 4 threaded metal spacers, so I can get 5V into it and the GPIO out on the 40 pin header. That would cover everything I need to do except getting video to the outside world.What I would love, ideally, is a HDMI plug to PCB header that would enable me to connect it directly to my carrier PCB.I'd only be making about 50 to 100 of these units, so getting something custom made would be too expensive, I expect.At this point the project is just an idea. I have to work out if it's going to be practical and economically viable.

content: Because of the delicate nature of the connector and the impedance requirements, etc, I would be more inclined to extend the USB and LAN connectors around the corner to be on the same side as the HDMI.However, there DO appear to be HDMI panel extenders available from several sources online. For example...http://m.allputer.com/mobile.php?main_page=product_info&products_id=1976

content: Thanks for the reply, Richard.That cable looks like exactly the sort of thing I want except at 30cm long it will be difficult to fit in the case I have in mind. However, at a pinch I could do it.As for extending the other sockets; there's 2 problems with that. Firstly, I'd need to extend 5 sockets rather than one. I don't know of a clean way to extend those either.The other problem is that the audio and mini-USB sockets would also need to protrude and I don't want people plugging things into them.

content: This would kind of work?http://www.angledcables.com/right-angle14.htmlI have bought several strange right angle USB cables from this company and all are good quality. No experience with their HDMI cables.

content: Thanks for the reply. The left hand version would do except there is no way to mount the socket end cleanly.I've just ordered a couple of these to have a look at. They'll take about a month to get here. Hopefully I'll find a better solution in the mean time.http://www.ebay.com.au/itm/111651724401

content: That's very similar to the eBay ones I've ordered, but slightly longer.
