I was just joking about the some assembly required- they are just 3/4 sheets of melamine for the cabinets. I'm making the boxes myself. The plan is Dominos to align and pocket holes to hold together. 3/4 for the boxes and 1/4 melamine for the backs. I'm using the adjustable plastic feet for the fronts and resting the backs of the cabinets on ledger boards leveled and attached to the walls.
Adjustable Shelf holes will be routed in with a jig, and I'm going frameless with painted Alder door frames (mortised with dominos), painted MDF Beadboard panels, and cherry drawers. Toe kicks will clip onto the adjustable legs.
I looked into getting the boxes made but couldn't find them for a reasonable price when compared to just buying the melamine. Total price for all the basic materials (11 sheets 3/4 melamine, 3 sheets 1/2 melamine, 5 sheets 1/4 melamine, 5 sheets of MDF, 75 bf of alder, 50 bf of cherry came in at about a grand - delivered to my shop. This was cheaper than even non-custom boxes alone from IKEA, let alone boxes and edgebanding in custom sizes.
I have the space to build, and am fortunate to have the space to store (100 x 66 foot barn + outbuildings) while I build in batches.
I'll post pics as I go along, but it is looking to be quite an adventure
I am going to do as some suggested, though and build BEFORE I tear out the old cabinets
