"The 600 servers are all still missing, the Associated Press reports. Which is no surprises: x86 kit is pretty generic. The real prize inside a bitcoin-mining rig is either GPUs, RAM or nicely fast solid state disks."
Bitcoin mining is typically done with ASIC miners, not GPUs. Mining Bitcoin with a GPU is a waste of time. If they were actually x86 servers, they were probably Etherum or some other alt-coin. Etherum is best mined on GPUs.
Miners typically boot off of a USB disks, not "fast solid state disks". You can boot ethOS to mine Etherum on a 8GB USB stick. http://ethosdistro.com/
The real issue is the video cards have gotten expensive. The video cards were probably removed from the servers, and the servers dumped at an e-waste site. The video cards were probably re-installed into new servers and went into a new DC. The serial numbers are pretty hard to read, and no one is checking where the parts came from.
