Welcome to OSXlatitude Sorcerer,
Here we use the excellent tool myHack by Conti to build our OSX's. If you game, I invite you to test it out. You can start by following the process here.
You can skip the EDP part since this model is not added yet. Just follow the USB Installer Creation and the Installation steps. Use my bootpack to replace the generic Extra folder. You have pretty much the same specs as my E6420, I had to replace the Intel centrino wireless with a Dell DW1510 wireless card, works nicely.
Post back your success or failure.
JL
