This build was meant to run Photoshop and store lots of RAW photo files, and the reasoning for that is my mom runs a photography business and needs to store the original photos. This computer is usually moved once a week for her 2nd job that also requires Photoshop.
Cable management in this case was ok. Instead of using only one SATA power cable for both hard drives, but the only two hard drive mounts were too far spread out for the cable to reach. Its not a big deal though.
Other than that issue, the building process was pretty straightforward. It only took about an hour and a half, and i didn't have any further issues.
The GPU was just an extra one I had sitting on my shelf. I thought it would help with the photo rendering or help Photoshop run all together.
