This is incredible! I didn't know this was possible. I swear by my 2011 iMac. Bought it maxed out and its performance hasn't let me down as a software developer and artist. I installed 16gb ram, an SSD but soon after the optical drive died so it has never really been as perfect as it could be. Over the past couple of years I had that display backlight problem that seems fairly common as far as problems go, and I damaged the thunderbolt port which in turn has made USB a bit problematic. So I've been tidying up the system. So far I've ordered a new logicboard, optical drive, and a newer HDD just to prolong its life as much as possible. I had NO IDEA I could upgrade the wireless module! I really just want it for the Apple Watch unlock feature because it makes using my newer MBP so much easier. I'm ordering the upgrade kit now!
