Re: having 1x 2.5 and 1x 3.5 possible? Or having 2x 2.5 and 1x 3.5 if the CD tray is replaced? the case naturally accommodates two 2.5 or single 3.5, but not both.  When you replace cd tray you add one more 2.5.  Basically one 3.5 takes up space of two 2.5.  In terms of max out number of storage, three 2.5 is way to go.  There are only three sata ports anyway on motherboard.  You can add a PCIe ssd too.
Looking to have at least 2x 3.5HDD's in the Dell. Is there a good way to go about this? There currently a caddy available for this?I haven't been able to find anything in my search but even if there is a CAD file for 3dprinting, I would love to know about it! Thanks in advanced!
