KC868-UAIR inside case - how does IR receiver see signals?

[dmshimself]

I'm hoping my KC868-UAIR works with all its devices and in preparation for that I've looked at the tower case the board goes into.  The IR receiver is to the left of the 2 USB sockets on the board, but the case has no clear window for IR signals to go through and reach the board itself.  Also I've noticed that the 4 IR transmitters on the board are placed close to the clearish plastic ring that runs round the outside of the case, but if the LED lights on the KC868-UAIR are on, will signals being able to get out of the tower case to reach my devices?

Has anyone used this device and is prepared to comment on the way the case works to let IR light in and allow IR light out when the lights of the KC868-UAIR are on?

LED and IR can work at the same time. The infrared signal can penetrate the transparent plastic part. Note: the transparent plastic part

Many thanks for that. Appreciated
