Millenium Rackstand 6U

The stabilising bar across the top blocks the use of the top unit!

That bar is a bit too short too. The two sides of the stand tilts a bit inward due to this, so they are not parallel to the edges of the equipment. It does not look good.

You can use the lowest unit space if you have something only 12 cm deep (including whatever cables sticks out the back of the unit). On the third unit space counting from the bottom, I have a 29 cm deep unit that stops only 2.5 cm above the table. So already there, you may have to use angled plugs for your equipment if you have something this "deep".

If you consider it a 4U stand for short items and a maybe use a blanking plate in the top spot to hide the stupidness of the top bar placement, you may be fine.
