XPS 8940, add 2nd 3.5" HDD

My new XPS 8940 has a 256 GB SSD and a 2 TB 3.5" drive. I would like to add a 2nd 3.5" Hard Drive to the enclosure. The chassis currently has a couple of unused Hard Drive cages. One of them is 2.5" and appears to be riveted to the chassis. The other unused cage is slightly bigger and held in place with screws, but still looks to be too small to fit a 3.5" hard drive. 

Is there any way to replace one of the smaller unused hard drive cages with a 3.5" cage?

@Tarak Abu Adam glad to hear that. Out of curiosity, what specs do you have running in your XPS if I may ask?

Here are my specs:

Until now, I have done nothing except open the case of my XPS 8930 (not a 8940), bought in early 2020). It came with a 2TB HDD and a 512GB NVMe drive. I can't recall the PSU size, but was I was deterred from going further just by the lack of space for fitting another HDD. 

Could I just replace the 2TB Seagate with 8TB or 10TB? - if there is room.

@WesternWombat  Your XPS 8930 has locations for two HDD at the bottom of the case, so you would be able to add a second HDD without removing the first one.  See the image below.

Great - thanks for the image.

I have a large 3.5" I can use there. I'm assuming the PSU is OK as I don't have much else attached. It's a fairly standard graphics card; i7 9700.

This thread was long and not sure if the answer is clear to me.  XPS 8940.  It already comes with a 2 TB SATA HDD.  Question:  Can I add a second 3.5" SATA HDD in one of the empty cages?

@XPSUser123ABC  Yes you can, it will go in the second 3.5" HDD cage below the optical drive.  That is, unless you are concerned about the thermals in your PC and have started the modding journey including moving your 2TB HDD to the top position and replacing it with a 120mm fan.

If you get 2   3.5 caddies for the bottom you can put 3 drives in.  If you use 2 R494D you need 2 Sata power splitters and 4 cables with 2X 3.5 caddy for a total of FOUR 2.5 drives.

Extra Cables

One 3.5 drive and One 3,5 caddy with

R494D installed inside it that holds 2 X  2.5 Sata Drives.

You then need extra sata cables and Dell SATA Power Splitter Cable 0N701D

120MM TOP Fan is 7M0F5  BRACKET 13P1-4ZN0201

120MM Front Fan is 7M0F5 but in a plastic bracket No Idea what that part IS

Still a bit confusing.  Let's say I just want to add ONLY 1 extra 3.5 SATA HDD of 4TB.  Right now as the XPS 8940 system stands - can I add an extra 3.5 SATA HDD?  

If yes, what else do I need to do?  Do I still need an extra fan?  

Is the easiest solution just remove the 3.5" 2TB HDD that came with the XPS and replace the 2TB with a new 3.5" SATA 4TB or 6TB HDD?  Unplug SATA cable and replug into the new 4TB or 6TB HDD?  Do I need an extra fan?

1518

OK.  Here is what I will do.

1) Locate the second 3.5" cage below my Optical Drive (I have a CD-DVD RW drive, no Optical Drive so will assume you mean the CD/DVD Drive?)

2) If I do the above, I will have no issues with thermals / heat?  

3) I purchase a 4 TB HDD 3.5".  Place it into the available 3.5" cage.

4) Plug the SATA cable (available in the XPS or do I need to buy one?)

5) Ready to go in the XPS?
