I have no affiliation with maker or seller but having bought 2 of these from the below addy I have been using my old 2500A as an external burner with exellent results. I replaced the 2500 with a 3500 just to keep things up to date in my desktop and could not see retiring a perfectly good burner and why buy an enclosure if you really don't need one? This adapter also lets you use old IDE hard drives as external though I would get a case for that unless you just need quick and dirty access and not planning to travel with it. Hope it helps.
