Create an external DVD drive from Dell enclosure?

I have an external DVD drive which came with my old Latitude X1, would be useful for using with other computers via USB:

But the connector is a weird proprietary Dell D/Bay plug:

1. Does anyone know how to convert this plug into something usable on a different computer without a D/Bay? Some adapter? I've Googled to no avail.

2. Does someone know if the drive that's inside the plastic casing is a standard drive that'll be compatible with one of the £5 caddy enclosures (images; USB powered) that are sold on eBay?

Here is what the drive inside the plastic case looks like from the back: 

Thank you in advance!
