Thoughts about drawer box construction.

All the drawers (and pullouts) that I have made had dovetail joints for the front panel, and dados for the rear panel, and a bottom panel that slides into grooves. 

That was the construction recommended in most of the magazine articles I read (and my primary source of woodworking education).

The front had to be the strongest as it would experience a pull each time the drawer was opened.

The rear panel only faced the inertia of the contents of the drawer.  So it did not have to be as strong.

The bottom panel floated within grooves to allow for seasonal movement of the side panels and front and rear panels. 

But modern drawer slide hardware greatly minimizes the stresses on drawer boxes.

Proof in point, the builder grade kitchen cabinets in my home had vinyl clad 5/8 particle board for the front, rear and side panels.  The bottom panel was plywood.  They were held together with staples (and no glue).  Only one drawer fell apart and needed replacement in about 30 years.  I credit the drawer slide hardware for the longevity of the drawer boxes.

Once you have the dovetail jig set up and the router set up, it is as fast as, or faster than most other joinery.  It is definitely faster than dowels, and possibly faster than dominoes. 

And the big cabinet companies have fully automated dovetail machines which you can watch on YouTube and see that they are faster than just about anything (including stapling).  So those manufacturers say, “dovetail joints are a must”.

Which brings up my question.  What is the fastest, easiest way to build drawers that will yield adequate strength?

I have two dovetail jigs and two routers that I used to have setup and ready to make drawers on a moment’s notice.  But they took up space that I needed, so they are no longer left setup.  When I had that setup it was a no-brainer.  The fastest method was also the strongest.

In terms of rating strength:

5 = dovetail joinery
4 = dowel or domino
3 = biscuit joinery
2 = butt joinery + glue
1 = butt joinery (no glue

Where would the Blum Metabox fit in?

Down here in Aus, the vast majority of built-ins have a melamine interior - usually white, but other colours as well. In general, they want the drawers to match, so double sided melamine on a moisture resistant core, 1mm thick ABS edgebanding, Dominoed together. I make them in a way where the drawer bottom is screwed up into the bottom edge of the box front and back, Dominoed to the sides. Very strong, will never come apart, without assistance.
I've offered dovetailed/box jointed wooden drawers many times, but only been taken up on it a few times.
The better versions of the Metabox are also popular - Legrabox, Antaro etc. They're not as robust, in my opinion, but work very well and look slick.
Been in the trade for 30 years and seen many variations of drawer making, but don't remember ever having to attend a job to fix a drawer box. Re-screw runners occasionally, but never to fix the actual box.

Re. the Metabox in your pic - when I used them at a company I worked for, I found that the sides flexed and put strain on all of the screw connections. Also, if the plastic 'dowels' aren't used for attaching the fronts, the small screws used would work loose and the fronts would shift.
