So while shopping around for a cheap Apple workstation my friend suggested I check out our campus surplus store. There I found a 2006 Mac Pro quad core with 4 GB RAM and no hard drive. The guy running the shop asked me how much I would be willing to offer for it. I quickly checked my phone and told that they're being sold on eBay for around $300 still. He offered to give it to me for $100. Now I know these models need a bit of work to get 10.11 running and finding a decent video card. Plus the special heat-sinked RAM is expensive and I would have to supply my own hard drive. But is it still worth it for $100? Thanks.
