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.
