floppys, cdroms work for sure most agp cards will work as long as you have the proper drivers.
this is what i found for xp.
Hello everyone
I have had a computer for about five years and it is now time to replace it. I have been reading about how easy it is to build your own so i decided to give it a go. The main problem so far is what is compatible with what. I spent a few hours trying to get the right parts and i think i have made the right choices, but i would appreciate it if someone who knows about these things would have a look at my basket and let me know if everything i have chosen is compatible.
