Yeah it's really quite an easy upgrade. Having said that, it took me 30 minutes! But I managed to misplace a screw which resulted in a rather long search around the house.
I lined my screws up as soon as i took them out. Im thinking of doing a SSD install. Is it worth the money?
Depends what money is worth to you and how much of it you have. lol.
People that fit the description above love it, and say "hell yes" to your question.
I do not fit that description. I'm broke as a joke, and feel lucky to have a MBP at all for my audio work. I also happen to need a LOT of capacity on my internal drive for audio sample libraries and three DAW recording programs.
My 500GB is nearly filled, so I won't be going SSD for quite a long time.
But if you don't need capacity, and you don't mind paying more than you will in a year or two, definitely do it.
When putting the back lid on, it doesnt snap in...
Just put the back into place and screw it down. The catches will then usually grab on their own. The next time you go to take it off, it will be snapped back into place more then likely. Just set it into place correctly and screw it back together don't worry about trying to get it to snap it together.
Line it up, Push down and put the screws back. The back 3 screws ( 3 last right screws ) are long, The rest are small.
Some parts click as there are grounding points that contact the casing if I remember correctly (they are looped copper contact/grounding points, can't remember if they are on the bottom lid or the around the logic board, seem to remember them being on the LB), and they click slightly when pushed on. It should be robust enough depending on how hard you pressed. As for the keys touching the display, that is normal. I always keep a micro cloth over my keyboard (screensaver from Radtech) to keep the oils from transferring to my display and leaving keypad marks. As for it being uneven, if that is true I would take it to the Genius bar and have them check it, as they can slightly realign the screen, unless you have bent it.
