I did the whole thing in about 90 minutes. I was stuck at step 18 for about 30 minutes though. The screws were held on too tight and neither PH#000 nor J#000 screw drivers were working. I finally placed the LCD panel in front my radiator for a few minutes and then used a flat head 000 screw driver. I don't know why this happened. The rest of the steps worked smoothly.
Yes, absolutely. I switched mine out with a Kingston 120GB SSD.
