I was going for an indirect lighting effect, so mine are wrapped top, sides, and bottom near the front of the box so it is harder to get a direct line of sight to an individual LED. I also made sure the interior was gloss white to tone down the reflectiveness a bit. However, I've seen a couple online with shiny interior and it doesn't seem to matter that much. I suspect you could cover the back panel and it would still look good, though it would make removing the back difficult.
