This desk is built very well, it is very solid and can house stacks of equipment.
It is excellent value for money, I doubt you could find something of this size cheaper.
However,
The rack holding bolts are non standard, they are fix turned holes, there is no give at all with these when mounting equipment.
Some equipment will not line up with say all 4 screw holes, so you have to use 2 out of 4 to secure the item.
( The mounting parts of all the racks need to be remade to the standard cage nut holding design )
The small upper rack fitting on the desk accommodates 5 and a half U, not 6U, although you can use the extra half U space has a vent space for say an amp etc.
The desk's upper shelf sits rather high, you need to sit on a stool to line up your eyes with a monitor on the shelf, you cannot put your legs under then because of the keyboard shelf.
(I have had to remove the keyboard shelf to sit at this comfortably with a medium height stool, I place the keyboard and mouse on the main desk platform, the monitor and speakers on the upper shelf.)
If modified like I did, this desk is very good, the build quality is excellent and the casters are brilliant, as moving it in and out over the years for equipment change has been made very easy.
The weight of my gear is quite heavy, it is fully loaded with equipment and is built solid enough to take it all on-board.
It remains excellent value for money for the features and space it offers, I have found a great way of working with this desk and I love it.
