Investigation finds inmates built computers and hid them in prison ceiling
Kind of shitty that they immediately used the computers to fuck people over...  The Ohio Inspector General says investigators found 
  an inmate used the computers to steal the identity 
  of another inmate, and then submit credit card 
  applications, and commit tax fraud. 

  One inmate, Adam Johnston, reportedly admitted to 
  applying for the credit cards, saying he just looked 
  through the ODRC system for a young inmate with a long 
  sentence, then used his information to get the cards.

You'd hope that, provided access to something rare, the use would be benign and reasonable.
