I guess I should add that S.E. will also sell you a P3 550MHz machine, with at least 128MB RAM and a 15GB drive for $20. And they'll throw in a free monitor. There isn't much reason to be limited to a bottom barrel low-end machine when there is better stuff available for less than a tank of gas. Unless one likes masochism. I can appreciate using very low-end machines for certain tasks, as I've got a pair of old Toshiba laptops that just can't take any more than 48MB RAM total. i've run DSL on those before.
