Inspiron 3670 Tower - Is it possible to upgrade the optical DVD drive?

Have a look at this thread.

You might go to the Dell Sales site and click the slider to chat with a sales person about which Inspiron can either be bought with or upgraded to have a BR drive.

And maybe contact Dell Spare Parts (1-800-357-3355) and ask if they have a suitable BR drive that will fit the Inspiron 3670. Have your Service Tag handy if you contact them.

But bottom line, if you want an Inspiron, then a USB BR drive may be your easiest/best option...

Firstly, I want to thank RoHE and speedstep for your inputs over the past 24 hours. I was doubtful that anyone would spend the time to help me with my question and I appreciate it since we all know what it's like to try and contact Dell directly to answer these questions (which isn't the most convenient). RoHE, thanks for referencing the other thread which talked about the external enclosure option (which I was skeptical at first, but this NexStar product appears to be better with USB 3.0) Here is the product link: https://www.amazon.com/NexStar-External-Enclosure-Blu-Ray-Drive/dp/B01MRUN0HQ/ref=cm_cr_arp_d_product_top?ie=UTF8 To your point, I think it's going to take a phone call or chat with Dell Sales directly in order to see if an Inspiron can be upgraded to the Dell Proprietary Bluray drive. Thanks to speedstep on sharing another external enclosure option (OWC Mercury Pro model) since other users may not know about other options. I don't know what the actual size is of the optical drive that is in the Inspiron 3670 (but it's looks like a 12mm). To close this thread, here are my final thoughts: Since I already have an older Dell Tower (that has plenty of room for anything aftermarket). If I ever wanted to go for the latest Dell towers (whether Inspiron or XPS), I would just have Dell customize the new tower with their Dell-Proprietary bluray drive and then buy an external enclosure (since I already have an internal 5.5" bluray drive) just in case the Dell-Proprietary bluray drive ever failed. Thanks again for your inputs since I'm sure there will be others like me who want to do more with just the standard DVD-drive. :-)
