Install Snow Leopard 10.6.8 on X58 i7 920 is easy, but Lion 10.7.1 is a little different, it needs some modification to the installer and the Lion partition. Tutorial is on the way. MSI platinum X58 1366 i7 920 OC to 3.6Ghz is a socket 1366, X58 chipset for the first i7 generation. This should work with all X58 motherboards. The important thing is to get the full QE/CI/CL, we must use a supported graphic card. We use Nvidia 8400GS, inexpensive and supported in vanilla installation for both Snow Leopard 10.6.8 and Lion 10.7.1.
