That's a workstation desk I was sure to check the weight capacity it's something like 200lbs per shelf so I knew it would be ok. I did check though, can't take chances
Here's my Cosmos 2 during install and post setup. I had to use my Dining room table to do the MB install it was quite tricky but the rails make moving the case around gently quite easy. I'm quite happy with the fan controller, tossed aside my previous 4 channel controller for this.
The only issue I ran into during the install was the Front Panel Audio connectors won't reach my Gigabyte motherboard as the connector is under the LAN which is pretty much the furthest away you can get. I'll see if cutting some of the built into cable ties gives it any more reach but I doubt it.
