Damn pissed about my computer.... Had a hard time trying to unplug all the cables and finding the slots to unscrew the components and hard disk out. Had to be very careful in order not to slam or drop any part... I'm too noob. I don't even know which parts are best left untouched. My brother's computer is worse... His is the type that is very unfriendly to customise. The holes are all out of alignment with the screws and I seriously have a hard time switching hard disks.... It's okay if you don't understand this part. I'm just typing it out for frustration....
