SM580 build complete!
You'll have to forgive the messy cable management (really should have opted for custom lengths, but went for default from CableMod as I ordered the cables before I got the case and wanted to make sure I erred on the side of the cables being too long... will likely measure next time and go for pslate). Will go back in later at some point to clean it up a bit, but got lazy.
Didn't have any issues with the build; quality and everything with the case is great so far, and I want to thank
@KSliger and team for their excellent communication from first email to final shipping.
