Hi, I'm considering purchasing a 2006 Mac Pro for mainly two reasons: 1) I need lots of storage space and am tired of plugging in various external enclosures and looking for the HDD with the right content on it. I was going to build a Linux system as a file server, but I'm having second thoughts. 2) Multiple monitors (I have three 24" IPS screens that I'd love to use, but at least two is necessary) Given the fact that I don't really want to build and maintain a Linux box to hold all the data, and 10.7 now has version control, it seems getting an old Mac Pro may be a very good idea. I don't do anything particularly intensive on my home machines, though sometimes I'll compile code locally (if I need the cpu power, I have access to proper servers). I don't play any games. I could envision ripping blurays occasionally, but I haven't ripped a movie in years. This Mac Pro has 12GB of RAM, which should make a difference in speed for most of the things I do. I'd throw in an SSD into one of the optical bays and add 4 3TB SATA drives controlled via a PCI card for SATA6gb/s. I use my laptop whenever I go out, which I'd access the Mac Pro files via the Internet. I'd like to be able to play a video on a Mac Pro and output it to my TV, preferably via HDMI. I'd not actively use the Mac Pro during the time I'm watching something on my TV, but normal tasks in the background may be running. Is the 2006 Mac Pro too slow to consider a useful everyday machine for me? I'm really not sure, but a computer from 2006 does not seem like the best idea... Am I wrong? BTW, can I upgrade the mobo, CPU and graphics card in a 2006 Mac Pro? Or is that not possible? I'd want to continue using OS X 10.7.
