Dunno if this belongs here or in The Lounge, anyway...
Looking for some recommendations for a 19" rack solution to save some desk space. Need to rack mount 1U + 3U units, max depth only 10-12 cm or so, including the cables sticking out the back. Something like this...

...but I remember reading in another thread something about K&M not being so sturdy, and the feet are about twice as deep as I need...
Any other suggestions, recommendations, DIY solutions?
