Yup; It comes with a manual, I/O plate, IDE cable, sata cable, a quick start guide and a software dvd. It also comes with a nifty GigaByte sticker too. Just about everything you need to get up and running minus cpu, ram, psu and video card of course. I know about those old Dells, I have a XPS T600 I bought new in 1999, it still runs, not fast but it runs Puppy linux good enough. Have fun with your new build.
