Electric power and wired ethernet to desk in basement not against wall
You don't even need a drop.
Just put boxes in the ceiling, or just below, and plug in. Your standard 6 foot line cord will reach the &quot;relatively low&quot; ceiling from the desktop, and ethernet drop cables are available in any length you like. Use cord/cable loom to &quot;prettify&quot; the cables if it makes you happier.
Alternatively, you know where the desk goes, so drop a false column (hollow, so you can hide boxes and cables in it) to that location - either onto the desk or all the way to the floor.
