My wife, IMHO, is an excellent photographer and I need to get her collection off a laptop and on to an actual workstation with color-calibrated monitor. We're a mac family and I've struggled with the lack of a high-end i7 desktop in the mac lineup. I was planning on the hackintosh route, but I've gone that way once before and I ended up selling it due to reliability issues. The post here: http://forums.macrumors.com/showthread.php?t=1609476 is making me seriously consider an old mac pro. Here's the list of things I want it to do: Make quick work of lightroom and photoshop and last me several years. I'm ok replacing the RAM and processors if it makes financial sense. Have sufficient storage to handle her half-gig of photos and our very slowly increasing 3TB media library (I'm selling our HTPC to partially fund this) Back up everything Be as cheap as possible I'm thinking of the following setup: MB535LL/A - I don't know if this dual-proc machine is the model to buy. I've read on macperformanceguide that for lightroom the single 6-core is the best bang/buck. I don't know if that's compatible with the older machines. 128-256 GB SSD boot drive 1x 2TB drive for photos 3x 3TB drives in RAID for media and Time Machine 32 GB of RAM Graphics card? Do I need it? What do you guys think? I'm mostly hung up on what mac pro/processor combination to get. I really like the idea of a $1200 powerhouse that I can spec out.
