I have an early 2008 iMac (Core 2 Duo 2GB ram, 500GB HD) that has been replaced with a newer iMac. I have Mavericks on it. Can I install OSX Server from the App store for $20, then install own cloud and use this as a file server? I want it to essentially replace dropbox. Can the computer be asleep or does it have to be awake all the time for me to access it from other computers? Any other reasons this would or wouldn't work? Thanks in advance to anyone who has some insight!
