Ranger, I think that is what I'm going to do. My total photo and music library is just shy of 500gb. I still take pics but not nearly as much as I use to, kids are getting older and don't play as much sports.
My other idea, and the wife said I'm crazy but I though I would run it through here. Back in July of 03 I build an i7-4770 system with an Asus Z87-Deluxe mother board and 16gb of ram and a 480gb ssd, rock solid for the last 3 years. I also have an i7 Macbook Air 11" with 8gb of ram and a 256gb eSSD drive. My thoughts were to load the Asus board, CPU, and ram into a LIAN LI PC-Q25B case and add my drives from busted N40L. Then I can use my i7 Air as my primary computer with docking station to drive my 2 dell 24" displays. Most of the stuff I do now a days is email, surfing, some light photoshop work, lightroom activities, and I think the i7 in the Air can handle that all just fine. Throw the 480gb SSD in a case and use it with the Mac for extra storage. Now it does sound crazy.
