Love this shelving unite.  It is attractive and of good quality.  Priced very reasonabley.  Some reviews mentioned that it didn't fit around plumbing....ours didn't either.  Before adding the brace closest to the floor, I set the unit in place and then added the braces.  No, it can't be removed without disassembling that bottom part, but, then, there really isn't much chance I'll be having to move it anytime soon.  Love the look of it.., easy to clean, and good sized shelves.
