I have a Dell 8200. P4 1.7 williamette. 640Mb RDRAM. I was thinking of replacing the Dell custom Intel mobo with one I can overclock. I do not want to spend too much money. I found an Aopen AX4T-II for $36. Also, since I have this custom Dell board that has a custom Dell power supply and connection that only works with Dell mobos, I will also have to replace the Dell case and power supply. I was thinking of a Chieftec SX1040 with a 420W PS ($74). A few questions: is it worth OCing? are the mobo & case any good? Thanks.
