Have a quad q6600 with a bunch of drives and 8GB ram. I'd like to turn it into a network time machine storage unit for my iMac and my wife's. Is there anything else mac related that I can use this machine for? Feels like a waste using a quad and 8GB for just network storage. What OS would you recommend putting on there? I have licenses for Win7 and Win2008. I've seen some tutorials for ubuntu but had a lot of difficulty getting it setup on that machine.
