Building cheap case for USB audio card called SkySong

Cheap case for USB audio card called SkySong

Goal
+ cheap and useful case for SkySong USB audio card;
+ appearance of device suitable to wooden and black case of headphone amp;
+ case must increase total weight of device due to lightweight USB card, which seems to have less weight than cables for connections;
+ additional Ethernet panel connector for I2S output;

Project realisation
* wooden bottom case machined CNC - especially enlarged for increasing total weight;
* printed 3D assembly elements: internal frame; front and rear plate;
* plexi glass top cover laser cut;

Summary
Device is working as expected, tested via outputs optic Toslink and coaxial digital RCA. I2S via Ethernet still is waiting for start off. Card is ready for using on Windows 10 and newer immediately (USB audio driver 2.0 is present in standard installation), but on older systems user need to install proper driver (tested on Windows 8.1).

    I think you might want to add more air flow.

    Wood is a good insulator and you can build up a lot of heat.

    You have right. Thank you for you comment. This is weak site of this housing. Hope there won't occur any major issues with temperature. Before I have started to build this case, I have tested this card sever hours, I have not discover any particural hot componanets. I hope I do not have missed this issue. Have you got some experience with this board?

    I have grind manually in black plastic 1 to 3 mm almost invisible clearance around connectors (power, USB and ETH) to get air flow from both sides. Thanks for the comment.
