Hi, I have an Acer Aspire 5600 (5601) notebook computer. I am looking to put an internal bluetooth module / card inside. Will this work? If so, which module do I need? Where exactly does it go on the boad?

I am also looking to upgrade my video card. Is this possible with my current motherboard?

Also, when I opened up my computer, I noticed right above the memory slots, there is a single, larger slot that is empty. What is designated for that slot? I have a picture if necessary.

Thanks
