Ilo dvdr04

I have a Ilodvdr04 that works from time to time. I want to replace the dvd burner with an internal dvd burner. Is this possible and will I have to replace anything else? If it is possible any recommendations on a replacement dvd burner? Thanks

What is that u’ve got again?
Depending on how old the PC is u may have to replace IDE cable from 40 to 80 wire one. How fast is the CPU?
