Im also not sure if i have right size/type screwdriver. Messing with cables is also difficult...
Cables aren't too difficult to handle, just gotta look for ends that look similar and fit together. Other than that managing cables is fairly easy, if the case allows for it.
The laptop you posted might be able to run Minecraft okay. I have a laptop that has lower specs, with the OptiFine mod, gets about 20 to 40 frames per second.
