Hello all, and thanx all the comunity forum.

I have this one:

Lenovo Thinkpad Edge E330 i3-3120/4GB/500GB/13.3" updated >> Lenovo Thinkpad Edge E330 i7-3612QM/8GB/250GB SSD/13.3"
Corsair GS700
Ati Sapphire HD 5850

I think I need PE4L-PM060A or PE4H-PM3N-060B (the PE4L is cheaper), I don´t know if I´m right. The PE4L is the best option in my opinion.

I read a lot of guides, I´m a little confused with a lot of material, manuals, etc.

This is the service manual show can connect msata and wan in pcie port, i dont sure if is posible conect the PE4L-PM060A in this port without remove the original WIFI card.

Is this a option too?
