This is quite a simple little rack piece. Just pay attention to the direction of things when you asseble it. It's easy, but I got one rail wrong so had to start over haha.
5 stars on features.. well, it doesn't have much, but what it has works like a charm. Nice blue leds too when it lights upp. Very Star Trek and that's always a good thing.
Extra bonus is that it can stand very stabile by itself on a table top with modules in it. So, it can be used on desktop too even if it may not be intended to.
