Oh yeah, the specs of the computer are fine, even better than the macbook pro's which are double the price, yours has better graphics, memory, bigger screen, same processor, good hdd. You're okay with the parts you chose.
well iam not as experinced as i should be so im buyin the laptop then a comp kit to pracitce wiht a dremel and building a cheap one then build my rig in the spring
well you have been here a while, as long as you arent wearin wool slippers and rubbing them on the carpet while installing your parts you should be ok. I have stripped my computer about 3 times now and put it back toghether to paint and mod. and it hasnt had any problems yet.
