You should go with the sleeving. Specially since the HDPlex 160w is so small we hava a lot of room to spare. The build would look so much cleaner and would match your selected theme.I was thinking of sleeving my HDPlex and then decided not to because its a giant PITA to do but yours looks fantastic and now I'm leaning towards doing it. So thanks for that (he said sarcastically). And I love the color you chose for the acrylic. Normally Noctura components just look terrible in my opinion but the sepia toned acrylic really brings the whole look together and actually accents the Noctura color pallet which is something i didnt think could be done.
