All,
Thanks for the replies. I basically followed the advice of Acova and SIW2 - I went through each of the devices listed on the support page for the computer and looked for a Win7 version of the driver. In some cases, the default version seems to work across multiple OS versions, in others, there are Win7 specific versions. Following is my working list - perhaps someone will find it useful (In each case, the first lien is copied from the MSI site, the following line(s) is what I found:
1. Chipset, 2. Intel VGA, 3. nVidia VGA, 4. Audio, 5. LAN, 6. Card Reader 7. WLAN, 8. BT, 9. Touchpad, 10. ME, 11. USB 3.0, 12. Radio Switch, 13. Others

Based on this, I have a high degree of confidence that I can get Win7 running on this computer.
With regard to reaching out to MSI for their tweaked drivers: Something to consider. This will not be my primary machine, thus getting every last bit of performance is not critical.
With regard to dual booting: Not worth the effort. I have ready access to several other computers, so I do not need to go this route, but this is a good suggestion for someone buying their first machine.
