[Alex Chooi]

Hi! Everyone How's life? I'm new in Linux. I would like to buy a computer for Linux. I heard from my friend, not all system suit for linux and it will hang if not compatible. Thus, I planning to buy a computer that is compatible to linux. I would like to know any idea if i buy dell P4 computer or IBM P4 computer? Please advice me if any. Thanks you   from alex
