its easy to assemble, and as you can see ample space for my systems, also nice and slim, not very bulky, it does comes with no racks, you should add those, if you would need then, I source the ones you see, from a sysrac I replace with this one, the other one was just way too bulky and everything got hot inside even with 4 fans insise the unit.
I was not especting this to be good actually, I mean it is not very expensive, also, this unit has the back and front open, but as long as it is against the wall, and good wire management, you should be just fine.
if you are just looking for a functional U18 rack, and you just want function, I recommend this, again please do your research, on how many equipment pieces are you going to put in there.
