Hi I also have the HP touchsmart IQ810 and I bought it about 2 days ago I also wanted the wall mount for this product but I have been to every single tecnology place there is and they all never heard of it so I email the acutal US hp company and they told me that they will release the wall mount this year in europe in this april 2009 I hope this information will be usefull for you.

Do you think that it looks better on the wall or on a desk I want your full opinion thank you!

well here it is. the first to be approved by HP as mentioned by the manufacturer.

this is the kit needed to wall-mount 500 series touchsmarts. you just need to purchase the mount kit [flat wall mount or articulating].

This looks like a nice mount. It's expensive though, considering the mount for the 800 series is only $49. I wanted to wall mount mine in December so I got impatient and bought the IQ800 mount. It doesn't have the same hole pattern required for the 506 and sticks out a little on the bottom, slightly less than the feet. I drilled out the proper holes and made it work and it has been fine for me. Aesthetics are secondary to me so it's fine, although I don't think it looks too bad myself since the adapter is black. I ended up doing all this so I could use it in both my bedroom and my Trailer (RV). I purchased two of the same wall mounts and installed one in the RV and one in my room, now I can move it back and forth between them pretty easily. Given the walk-up usability of the PC, it's a good candidate for wall mounting and it has been great to have in the RV when camping.

From start to finish the whole thing probably took 2 hours, some of that time spent contemplating what I needed to do and some of it spent installing the wall mount to use with the adapter.  This first picture shows the original stand on top and the 800 wall adapter on the bottom.  Clearly the hole patterns are different.  I don't have pictures of the final product so you'll have to use your imagination.  Essentially I drilled four screw holes to match the table stand and one large hole to allow the spot for the memory cover bolt.  It looks to me like they used all five screws for the wall mount on the 800 series, but I am only using four.

This next picture shows the profile view.  You can see that the bent tabs on the mount plate are different as well.  I ended up just bending them flat on the wall adapter since they didn't match up at all.  While it would have been nice to have the tabs since they will help with the load on the mounting screws in the bracket, I'm taking my chances that the screws alone are strong enough.

Lastly, the part that isn't visible in any pictures I have is that the cover (I think it's the memory cover) that goes around this mount has slots in it to accomodate either the table stand or the mount, the problem is that the slots in the cover aren't quite long enough to accomodate the wall adapter so I had to lengthen them a little.  I was a little disappointed to have to alter plastic, but I figured what the heck since it was only cosmetic and on the back, and the lengthening was only a little bit.

Once the bracket is attached to the PC, an adapter plate with the rubber feet against the TouchSmart then bolts to the bracket in the pictures above.  That plate then attaches to your wall mount.

Here is a view from the front with it wall mounted.  You can see the bottom of the adapter sticking below the unit.  If you're looking for perfection, then this isn't the solution for you.

Here is a poor picture from the back side.  

I just re-installed this after brining it back in from the trailer when I took these so the cables aren't neatly routed, but that's about it.

The wall mount is an AVF Vector. I got it at a local hardware store and I believe the cost was near $50 but I don't remember exactly. I did a little searching for mounts and found a wide range of choices on-line, but in the end it came down to finding what was available when I ready for the installation.

Bottom line is that you can use any VESA compliant mount with a suitable weight rating. This particular mount swivels 180 degrees at each joint and the swivel at the display allows movement to tilt up, down, left, right, and some rotation clockwise/counter-clockwise. The tilt is great for setting the right viewing angle when sitting across the room. The TouchSmart is definitely a heavy unit so I was worried about the mount being strong enough, but it is definitely sturdy as-is and I'm happy with it.

Good luck.

This is the mount here:

One interesting thing to note is the box I have states the weight capacity as 30lbs, but the web site shows 66lbs.  In my opinion, 30lbs is about all I would trust on this.   If I remember correctly, when I weighted my TS it came out around 24lbs and it feels pretty solid on this mount.

I purchased the mount at a Friedman Bros. Home Improvement store.
