This makes no sense financially and if it's going to be hosted in a data center it should be using specialized GPU mining racks that can run more GPUs per motherboard/CPU.  You really need open racks and to use PCI-E riser ribbons if you want to build a GPU mining rig, using a desktop computer case makes no sense especially because heat is a huge issue with scrypt mining.  Also to be honest, scrypt mining is VERY finicky compared to SHA256 mining, you're talking about constant lockups and crashes if heat isn't perfectly controlled.  The amount of time that's going to go into keeping everything running is going to be much higher than with bitcoins and given how the Bitfury towers already caused a ton of problems I'm not sure the coop has enough manpower to keep racks of scrypt miners up and running.
