M-153x Details and upgrade info (what are you upgrading on it?)

I don't see much on these forums or any other forums in regards to this machine. It runs on the mobile intel 965 chipset and it seems to have pretty good potential for gaming with a few upgrades. I just bought one and it is my first laptop and I want to see what others think of it and hear from other owners about what they are upgrading and what is best to upgrade. What kind of gpu can you put in it and i'm also interested in possibly doing a screen swap for a higher resolution.

Where is a good webby to purchase a screen from and around how much do they cost?

If you own something similar to the M-153x any information is very welcomed just for curiosity sake and maybe some others are interested also.

I am also curious about others daily experience with it. About how much time do you spend on yours and the duration for which you play games. If you leave it on overnight and what settings you use for like downloading and such overnight is this a goodthing to do? With lid closed or open? things of this nature. Thanks for any input on any of these matters.
