Its what I use, you must have SP3 and just follow all the instructions.
The only drawback,if you screw up installing the shell or the start up animation it wont even start up.
So yea its risky but if your good with computer go with it.
To do this you need to hack some of the system files to get it looking as good as it looks on there though, I'm installing the custom boot screen soon.
