Default Sleeves vs. Hard Pipe

Sort of a poll...who out there prefers to drop a sleeve through ceiling and then expose cabling into the wall-mounted rack. Or...Hard pipe EMT out of rack into ceiling? Either 3" or 4" EMT

Scenario:
* Sheet rock ceiling
* Wall-mount rack (24"x22"x35")
* Top of rack 3 ft from ceiling
* Single story bldg, roof line is 18" above rack location
* 75 ea. Cat6 cables.

Would rather have the conduit end before the rack if that's what your asking.
Also prefer EMT all the way from the rack to the box.

If you pipe it from the ceiling to the rack you can be a slob and not comb out the bundle and nobody will know. It will be easier to do adds, and if the maintenance man or cable guy runs a cable their mess will be hidden.

If might depend on whether I have a 3.5' piece of 3" or 4" EMT around.

(Does the back of the rack have a big enough KO? )

We sleeve through ceiling and have exposed wiring to racks more than piping it.

Yes...has knockouts up to 4"
My original thinking to pipe all the way to "dummy proof" future adds

Are you talking about a wall mounted patch panel, or a "Hoffman box", IDF?

Here we almost always pipe all the way into those wall mount rack enclosures. I think it looks better when you have a totally enclosed rack, a lot of places paint the EMT to match the wall too.

I'd say unless the spec says something different piping right into the rack is my preference for appearance and ease of future wiring runs.
