Changing Computers

I have been a little dissatisfied with Apple's hardware current hardware direction and offering for some time.  I used to have a 2011 MacBook Pro and with that Laptop I could open up the chassis and upgrade or replace the memory, the hard drive, and the optical drive.  I liked having that flexibility.  Now Apple is on a quest to make everything smaller and lighter and they make their laptops so that things like memory and hard drive space are not user replaceable.  Really don't like that.  I like Mac OS but I really am getting irritated with Apple's hardware direction.  I have also decided that my computer needs have changed over the last couple of years and I really don't need a laptop anymore.  I am thinking about getting a older Mac Pro or building a Hackintosh.  The Hackintosh would be the more current hardware but the Mac Pro systems are built like tanks and I have always wanted one.  Have been looking a lot lately for a good deal on a Mac Pro but have not found one yet.  I am leaning towards the Mac Pro even though it's an older platform.
