For all you Computer types, my brother-in-law wants me to bring him a 120gb hard drive. He says they cost approx $5000 rd in Santiago. Not being a computer person, will any hard drive fit in in any Computer. I belive he has a HP PAVILLION. Here i can get a seagate barracuda for $100 Canadian or a Samsung spinpoint SP2014N 200 GB for $130. ADVICE please.
