<p>Because of the never-ending upgrade cycle, I now own two mac pros: a early-2007 and mid-2010 which will effectively replace the 2007 as my work station. The older machine is frozen with Snow Leopard due to logic board limitations, hence the newer machine (Mavericks). But it still runs great, has 16GB of RAM and 4 internal drives. My other current hardware includes both a 4-bay and 2-bay external drive enclosure, an Epson 3800 and a two monitor setup.</p> <p>I want to utilize the older machine in an efficient manner but I'm not that versed in what role it could best serve. I do not need my entire archive on-line and don't have a need for a media server and don't completely understand how to implement a server either. The old machine can only run LR 4 but the newer one has LR 5 (both have CS6) and I feel that limits the role it can play, but maybe you have more informed ideas for me to consider.</p> <p>Looking forward to hearing your ideas!</p>
