I'm using a Macbook unibody from 2008 upgraded to 1TB SSD and 8GB RAM. However, I'm finding it is becoming unresponsive and things are starting to not work as well as they used to (i.e speaker and USB port). I'm considering buying a used Mac Mini from 2012 and replacing the HDD with my SSD and maxing out the RAM. Or buying a Macbook Pro classic - not the Retina - which would allow me to take the HDD out and replace it with my SSD. I could even remove the optical drive and put in a second SSD. Both machines have USB 3.0 and a SD card reader which my 2008 Macbook does not. In Apple's refurb store the price of a Refurbished 13.3-inch MacBook Pro 2.5GHz Dual-core Intel i5 is £759.00. This seems expensive for a refurb machine plus one with several years old internals. The Mac Mini from 2012 could likely be had for half the price from eBay or somewhere. I'm guessing I would use the cMBP closed for the most part attaching to an external monitor. However, the cMBP having a display means I could use it as a portable. Something I can't do with the Mac Mini. My needs are modest and while I spend a lot of time working on my Mac I don't tend to do processor intensive stuff. I will likely buy a Retina screen laptop in the near future but if you've got advice on whether I should go for cMBP or Mac Mini or neither do let me know. Any suggestions?
