To be honest, I've seen commercial 7' racks in data centres and computer rooms that were worse than the worst ones here!
I was once tasked with rejigging 3 racks in a remote computer room. The racks were arranged in an "L" pattern due to the constraints of the room. None of the doors - front or back - could close because of cables running between servers and switches. Some cables actually ran diagonally across the L shape. A lot of cables were jammed between the mounting rails, and 3 metre cables were used where a 50cm one would have done, or 2 metre ones where a 3 meter or more was needed. Almost nothing was labelled, and where it was, it was wrong. The cable colour coding scheme was ignored, and nothing was recorded. There were servers racked on a slant - TWO nuts off on one side - and even mounted back-to-front. Others were literally sat directly on top of other kit, not bolted in at all. RAID arrays for critical servers were mounted in adjacent racks, with the cables running around the opened rear rack door, and there were a number of suspicious, unmarked servers, of odd brands that were hooked into the main switch, that nobody could identify. One turned out to be an abandoned Nagios server, but one was never identified, and nothing broke, nobody screamed when I turned it off.
Just about all the horrible things you have seen or heard about were in that room. It took weeks to sort it out.
In 2011, I worked in West Bromwich, greater Birmingham, UK, on Birmingham Road, where it joined High Street. The news had been reporting on riots starting in Tottenham, London, and it was said that they were spreading. One lunch time during this time, I went out to get lunch from a great Indian sweet shop called Dhillons that did an amazing Samosa Chaat, which was about 5 minutes walk down the road from our office. As I got closer, I could see a crowd and police further down the road, not far from the sweet shop, and coming towards me. Then I saw smoke, and turned around, and went back to the office, without my samosa chaat. Loads of busies with full blues and two's on (police cars with sirens and lights on) started whizzing past, towards the trouble, and this continued all afternoon. When I left, the air was cloyed with smoke, and the street towards the sweet shop was cordoned off. The next day we learnt that the sweet shop got smashed up, and their van was torched, one of many that got hit. Nearly got caught up in a riot!
