If you're a DIY type person I think you could make it work, but probably not out-of-the-box. There's no groove for it to go in to on the sides so it would just be sitting on the french cleat, thus would be too risky even if were able to stay balanced. You may be able to nail in something to add sort of a groove, but may or may not be worth the risk.
I started out using one of those but ended up switching to a full adaptive reef cabinet. i just had too much cabling and power bricks that couldn't fit in the back of that panel and it ended up looking pretty bad. I think it could work well, however, for someone with less cabling and power bricks.
