'Built-in' Bookshelf-Ceiling Gap

Hi everyone! I am new to this community so forgive me if this is posted somewhere already. I am doing a lot of DIY in my new home and my wife wants bookshelves to have a built-in look. We purchased uppers and lowers from IKEA that will total 84'' in height and the ceiling is 96". She is telling me that they need to reach the ceiling and finish with some molding to have a truly built-in look. Would I just build out a 12'' tall box to fill the gap, then trim it up clean?

Hi All,
New here and my wife just got me a portable TV to watch sports when I’m in the garage or on my deck. I have been using an old Roku to Apple TV stream from my phone to the tv using Streamed but this site isn’t so reliable with casting. Any way I can hack my Roku or another device to stream all MLB games direct from the device? If this isn’t the right community, I apologize!
