Thanks so much, really happy to hear you like it!!
What helped me a lot was to have a real (and destroyed) hard drive and screwdriver to really understand the materials and structure of them!!
Also, chosing a “dynamic” and not too boring angle to place the camera was pretty complicated, i tried something like 5/8 different camera setup…
Yes to have the physical object that you are modelling and texturing in front of you helps considerably. Finding that perfect angle can be a pain, I use blenders stored views to setup multiple cameras and experiment, but you found it.
I really like it - also the colors and the light and it’s so realistic. I guess the reason for opening a crashed hard drive wasn’t that funny, but afterwards it was a good thing 
Thanks, Happy to hear you like it!!
