Hi. Two questions. I am from Greece. I ordered the: 15'' 2.2 with upgrades: -2.3 GH -8GB Ram -128 SSD -Hi-Res Display Glossy. 1) Cause of the Hi-End 2.3 model its more possible for me to have noise and heat issues? I want to ask if everyone of you with this models have heat and noise problems or some bad productions models. 2)I want to buy a sleeve case and i think of buying a colcasec. Have anyone of you this case? If yes it's good? Or something similar and better.
