Hi bro, where did you buy the Antec Fusion casing? Which PSU are you using?

I see, thanks.Sigh.. why all the good stuffs always in SG first.

I found these 2 remote and IR receiver kits in Amazon, less than 23 USD including shipping to MY.
HP seems to be a better choice because the receiver is smaller and there are reviews saying it is working and you can use the remote to boot up and shut down your pc.
However I bought the Lenovo kit because at that time it did not allow shipping of the HP kit to MY. Now it does, just a few days later.

HP OEM Windows 7 Vista XP Media Center MCE PC Remote Control and Infrared Receiver for Home, Premium and Ultimate Edition

Lenovo Microsoft MCE Media Center Remote Control USB IR Receiver RC6 KIT

Overall I'm quite satisfy with the Lenovo remote, though sometime the arrow keys are a bit lagging.
The IR receiver is eHome/RC6 compatible. It also came with what appears to be an IR emitter.

I use it with XBMC MCERemote plugin. Once the builtin settings are applied (and reboot) most common keys work.

By default, the power button will put your pc into sleep and also wake the pc from sleep. I have only tried with S3 sleep mode. However, I mapped the power button to alt-f4 so it can shut down XBMC and also windows. I also mapped the Windows key to start XBMC.

Looks good.
