Anyone have recommendations for cost effective rackmount cases you can convert a tower case . I have a truenas system setup in a tower style case and I kinda want to mount it, it just sits on top of my rack. I figure any of the 100-200 dollar ones would work, but just curious if any stand out for anyone.

Yes I know everyone like proxmox, but I'm hoping to find a gui for kvm that might be used in an enterprise. I want to learn more about kvm for my job, but until proxmox gets better, we will not be using it so I don't want to get used to it. I've been trying sunbeam to do openstack on ubuntu but I can't get it to work with a bonded interface, and just wondering what some other options are.
