Hello, I'm wondering if any of you have ever took your iMac to MicroCenter to be upgraded. I'm willing to upgrade my iMac 2007, Core 2 Duo 2.0GHz for a speed boost, and don't feel like buying a whole new machine. I mainly would just like to upgrade the HDD to an SSD, and I read online that you can replace the processor. The processor part is not necessary, it handles medium Photoshop editing. I think the main issue is my HDD. I just want to upgrade to an SSD. My question to you is: How much would it cost? Amount of time it'd take to upgrade? Can I use the old hard drive as a Time Machine backup but as an external?
