This I/O module for the N600 contains:
- 2x USB 3.0
- 2x USB 2.0
- Audio In & Out (supports AC97 / HD Audio)
- Power/reset switch
- Power/HDD LED's
- On/off switch fan LED
If you have a problem with the I/O panel on the N400 then get this as its near enough to do the job.
I actually needed the USB 3.0 ports which come as a unit within this module and they definitely can be transferred to the N400, the rest seems as near as compatible. I did have a conversation which lead me to believe that these weren't interchangeable, but they are. The switch for the fan light may need playing with if you do use the whole thing on the N400 though. But highly recommended.
P.s Cooler Master Europe needs a phone number, it would save a whole lot of time and having to phone America from the UK!
