i bought a ****in Acer 4 years ago and stuck in a baller video card. still a scream machine to this day.
funny story about macs. My sister bought one of those imacs with the computer build into the lcd display against my advice a few years back. after about 1 year the thing started getting so loud because of the dust buildup inside. Of course you cant open them up. It eventually overheated and melted down.
