Tune 3750 My first attempt with this adapter my Dell Vostro unfortunately failed. After call bie Salcar in Leipzig (Very good! Contact) I was no theater, ruckzuck "the other" version sent. DELL Vostro User should directly select the "stainless steel" variant. The boards are probably a little different, this works knotless and even takes the original DVD manhole cover on. Full star because nice and uncomplicated.
