Know for a fact that the EP45-UD3P works with snow... you have to have a newer mac book to make the restore image and add the right modded boot files. There is a guide to follow on this topic.... he even list the hardware he used and is know good just google lifehacker and you should find the guide. Make sure you buy the snow dvd... there only $29.99 good luck
I waited over a year and am loving it..... also don't have to use a 9800 gtx a 9800gt 1gb card works as does a ATI 4870 512mb right from the get go. All software updates as it should no problems at all.
