I have one of these lying around http://www.bluraysupplier.com/products/HL-GA31N-12.7mm-SATA-Slot-in-DVD-RW-Drive.html#.Wg1itGi0P-g and would like to put it in some sort of enclosure but for the life of me cannot seem to find anything. Probably using the wrong search words. Not looking to spend a fortune but it might be be more saleable if ? can offer an enclosure with the optical drive.
I use one of these : https://www.amazon.co.uk/Startech-Slimline-Enclosure-Blu-ray-drives/dp/B00VO7VOUI/ref=sr_1_1?ie=UTF8&qid=1510827637&sr=8-1&keywords=portable+dvd+drive+enclosure Our IT Team gave them to us with Samsung Slot Loaders in, and can't really say anything bad about them - Corners a bit sharp on one or two of them.
I'd have a look on the 'Bay in that case - No name ones are probs significantly cheaper. https://www.ebay.co.uk/itm/Slim-USB...332329?hash=item4d56f44ae9:g:7BIAAOSw4CFY2mG8
