Yeah i put a 6X DVD ROM and it works great.
I am thinking of getting a 16X slot pioneer dvd rom. I am also using powerdvd 2.5
The front bezel is a little difficult to remove... it's not as easy as as it says in the manual. i don't know how to explain exactly how i got the front bezel out... but I know for sure I was able to put it back in hehe...
Isn't it an awesome bookPC? I am getting a winTV GO card pretty soon and will be adding that.
