I've got 2 dells. 1 gateway. And 1 I believe someone Built them selves. It has an amd in it. I believe the rest are all P4s with pins. If if its a dell computer. Is it an dell power supply? Also 3 had 2 256 sticks ram. One of the dells had 2 20 hdds. Gateway had this pretty stick of ram. One of em had this pretty heat sink. What you guys think?
