The Streacom IR recievers are internal Flirc revievers, but they have USB dongles too if needed. Only problem is that IR gets blocked easy so the dongle would probably be in the front:

Thanks for the suggestion. IR receiver development, in my opinion, has taken a significant step back from the focus. The focus has turned from full automation to multiplatform cross compatibility and tiny, USB-port-sized form factor. These are remarkable strides forward, but the latest and greatest offerings lack one major feature that would give a truly hands-free experience: they cannot power on from S5. I did research into this corner of the market. The basic requirement is an IR receiver provide power switch headers to connect to the motherboard and case power switch. There are just three options available now that I am aware of that provide IR control via a USB header
and (more importantly) power on via an IR signal:
-FLIRC Streacom Edition (FLIRC-SE)
-Perfect Home Theater (PHT) IR receiver
-Inteset Internal IR Receiver
The PHT and FLIRC-SE are both compatible with Streacom's internal mounting patterns for their IR windows. Meanwhile, the Inteset is meant to be mountable via a DIY solution. Unfortunately, in my testing, the Inteset could not operate properly off of on-board USB power unlike the other two options and required using the included power brick. Because of this limitation, I strongly recommend either the PHT or the FLIRC-SE. Jason at FLIRC is working on releasing an updated version of the FLIRC-SE. It will have more responsive and accurate IR circuitry found on the current-generation version 2 FLIRC USB receivers.
