My three main Macs. The 2013 Mac Pro is my main machine and what I do most of my video editing on. It's the bone stock model, save for the additional 4GB of RAM I installed after I bought the machine (official Apple/Micron DIMM to match the rest, $30 on eBay vs $100 from Apple) and I'm currently looking into a 512GB SSD. Was bought refurbished from Apple in February of this year. (Note that I have San Francisco set as my font, that's why it shows up really weird). The 2012 Mac Pro is actually a 2009 that I upgraded. I went into a PLIST file and edited it so it would show up as a 2012. Found this machine completely stripped at a recyclers for $40 and rebuilt it and upgraded it from then to earlier this year. Currently serves as my backup machine.
Finally, there is my laptop. I owned a late-2013 dGPU MacBook Pro 15" Retina, but after it died multiple times due to GPU problems (which the two machines that preceded it also had within a year of ownership) I returned its replacement for a gift card and bought the 2013 Mac Pro. I needed a portable machine, so I bought this machine the following month because I wanted an i5/i7 machine at minimum. It's a bone stock late-2011 13" MBP. Overall the machine is actually really nice, just wish it was a bit faster for on-the-go video editing. When I got it a few months ago, the owner still had Lion installed and the original hard drive. As soon as I got it I put in a spare 250GB SSD I had it my Mac Pro, then last month I upgraded the RAM. Currently runs El Capitan Beta 3 (which I just saw is labeled as '10.11 Beta' under version number now).
