My new sideboard?  

it looks
like the TOP of a proper sideboard. Many had a narrow set of drawers on top of the main unit much like that. Like it and like what you did.

It's cool, but you are...
It's cool, but you are right. Loose the legs.

Like it.
Is that an inlaid stone top ?
It would be nice to see this once again wall-mounted, as originally designed no doubt. But, a single leg at each end (or at the 1/5 and 4/5ths points, say), nearer the front than the back of the piece, would allow it to stand on its own -- like one of those leaning bookcase units. Not a bad solution (particularly with a heavy top) and just as "modern" ?

Travertine on the top....

The legs have to go they are pretty gross if you ask me, wall mounting it is no problem for me...it needs to float to look right in my opinion.

Divine sideboard, vw!
It would look best sans the legs,mounted to the wall...in my home. I'd be tempted to mount it lower than the existing height.
Cheerio!

swing by WV and I'll sell it to you Mark...it'll give you a good reason to come visit.
Next pics will be on my wall next week Im hoping I pick it up Monday

I guess I'd call it a console table.
And yes, cantilever mount seems right if it was built for such.

You will find
holes in the back of your console. I would expect at least some of these to be very near the top edge of the back. These top-most ones are the most important fastening points, as screws or bolts (with flat washers beneath the heads) placed there will best resist the force of gravity.
In the US, these holes would be about 16" apart, as that is the normal (and code-enforced) spacing of wall studs. Wherever the studs in your wall are placed, that is where the screws or bolts should go. The cantilevered weight of this relatively narrow furniture piece (with its heavy top surface) will not be secure if fastened only to sheetrock or (in older construction) plaster over lath.
But you already know all this, I imagine . . . !

Actually this is quite easy to hang because It has 4 T shaped brackets that bolt to the wall first. The legs were added to the front because the previous wall it was installed on has no studs as it was an exterior wall of a very old brick home. I'll post some pictures start to finish of the installation.

This is more of a console table than a sideboard.
