AMD is a better choice, all motherboards now come with onboard sound. A 64bit sempron with a asus k8v-mx would be ideal and enough for the given needs. Cabinet with SMPS will set you back by a grand or so. 80 gig hdds are now entry entry level, get a 7200rpm hdd. It makes a lot of difference and the price difference is just a few hundreds. Dot matrix printers are costly, Espon or TVS are the main players which cost around 8k.
