Find some on the 'bay.  You will need a 9.5 mm slot load, check for returnable if DOA or not fit.

DVD RW, BD Combo. Blue-Ray RW

Thank you. Ordering something without knowing it will even fit feels a bit "shady".     

But thank you for mentioning Ebay. So far I only looked on the Dutch version of it. I'm going to try UK and DE.

Part-people sells genuine Dell parts and they have OEM drive for you here https://www.parts-people.com/index.php?action=item&id=34265

Yes, I found that store too, but shipping to the Netherlands is a whopping $30.    

I am looking for something closer/less shipping costs.
