Upgrading my Alienware Area-51 7500-R4

Hello,

I've got an older Alienware that I am looking to upgrade:

Current Specs...
AREA-51 7500-R4
D- CORE 2 DUO 2.13GHZ E6400 2M CACHE 1066MHZ
EVGA NFORCE 680I SLI MB
EVGA NVIDIA GEFORCE 8800 GTX 768MB PCI-E
4 GIGS RAM
NVIDIA 8800GTX

I'd like to upgrade to...
CORE I5-750 2.66 GHz 64 BIT
INTEL80 GB X25M MAINSTREAM SATA II SOLID STATE DRIVE
ASROCK P55 EXTREME 1156 MOTHERBOARD
8 GIGS OF SOME COMPATIBLE RAM

Alienware says that they won't do the upgrade for me so I will need to do it myself. I'm wondering if anyone has any insights as to problems that I might run into or if you think that this will be pretty standard install.

One thing that I am concerned about is the Liquid Cooled System. I've never dealt with a system that is Liquid Cooled. Does this present any special challenges or is it pretty straight forward?

Thanks for your help.
