Installation was incredibly easy. Drives, optical and hard were setup very easily thanks to their toolless clip and runner systems.
There’s plenty of room to install the motherboard and there was a tonne of room for cable management meaning most were out of the way thanks to 10 minutes and the liberal use of bundled cable ties.
The only minor headache during installation was that the small 2.5" HDD/SSD cage had to be removed to install the PSU. Unless you’re using a very small unit I don’t see how it would fit otherwise.
