Hello, I have a 2008 2.5Ghz Core 2 Duo 15" Macbook Pro. I have replaced the DVD drive with a 1TB SATA hard drive and likewise have replaced the main system drive with a 120GB SSD. It is also running with 4GB ram. The SSD has made such a performance boost to the laptop that it is quicker to load applications and perform well compared to my 2012 Mac Mini before I gave that an SSD!! Just wondering whether its worth selling? I've seen the original spec unmodified selling for approx £150-£175 GBP however wondering whether mine would sell for more because of the performance enhancements I've since made.
