From what little I could garner from Dell's tech support offerings, they have a P4 CPU, probably a socket 478, so it would be an older one. Two RAM slots, which hold up to 2gig of RAM, so it probably has 128 or 256.
It ought to rip OK. It's CPU and lack of RAM may slow it down, but I doubt that it would take all day or anything.
If you can post what its CPU and RAM are, we can give you a better estimate.
