Sorry but I HAVE to post a response despite not knowing the answer either.  I have searched the web for schematics that show the location of the secret HDD and so far haven't found it, just the same two obvious drive slots when you open the outside case.     It's right here.  You can see it after removing the panel, and without moving anything else.  I replaced mine with the Noctua fan.    [IMAGE]EVGA PSU[IMAGE]   [IMAGE]
I want to replace the 1 TB HDD but I can't find it. I've seen online tutorials about 3.5 inch HDD installations/removals and they all deal with the main compartment that is clearly visible right when you open up the case. That is not what I'm talking about (in fact, that was empty when I got the computer and I have since installed a separate 3.5 inch HDD that I purchased separately). I am looking for the 1 TB HDD that came pre-installed when I purchased the PC (and is definitely there as Windows sees it). I cannot locate it. All I see is two 2.5 inch slots for SSD's and one 3.5 inch slot for an HDD. Thank you in advance.   Here is the exact computer in case it's helpful: [URL]
