The Panduit stuff is OK, we have similar stuff over here. But I never thought it looked really really good. Although I haven't seen coloured conduit before (white/grey only) so that might look better. It won't match/complement the paint finish and may just look like I've stuck plastic conduit to the wall.
Very low cost isn't an issue. Quality of looks is the issue. I know cheap can be good. I was hoping someone may make a really good looking version of this split conduit. With looks to die for. I know they don't display the racks with wired kit on them but I want it to look that good.
Alternatively how about two 2inch chrome tubes (Power/Other) running vertically from the floor to the top shelf with dark grey plastic top cap and holes at specific levels to bring cables through. Or a slot that would allow cables through at any height. I could make one of those. See I have been thinking.
