After completing this build I realized the primary inspiration was to best reflect the beauty of the hardware, minimizing any distractions, and letting all the parts shine, thus the name Reflection.
The reason I don't have a large HDD is because of the case. I know this may sound ridiculous, but the position of the HDD drive cage made cable management in the back really difficult. I almost bought a new case, but just decided to go full SSD and remove the drive cage, finally allowing the back of the case to fit snugly rather than pressing in all the cords. This case is really beautiful, but the cable management in the back leaves much to be desired.
