Oh! I just redid my whole setup. It has doors and every system is all connected at once. No swapping cables.
I'm on mobile now, but I'll post a pic when I have a chance.
Edit:

Left side open:
Now I only have doors on two of the four columns of the shelving unit, I may add two more in the inner-most columns so that it's fully enclosed.
This is the
BESTA series from Ikea. And you can customize it however you want. You can get doors and/or drawers wherever you please or build it higher or wider, etc. Personally, I was going to replace this unit because I didn't think I could fit everything, but I did some re-jiggering and got it all to fit nicely. If I get one more system, however, I'm going to have a hard time finding a spot for it.
Anyway, before I re-jiggered everything, I was actually looking at the new
EKET series of shelving from IKEA that just came out. If I could do it all over again (and I still might) that's what I'd do now. They also have the
KALLAX series, but personally, I think the EKET is better just because it's so modular and customizable. And it has nicer colors too. BESTA, again the series in my pics above, is also fairly modern looking, but is a less "in your face" sort of look.
And yea, I know I need a floor rug. It would make the whole thing look way nicer. That's in the works too.
