I have 3 old servers and I use that term loosely, which are in huge towers. We are putting all of the servers into an APC cabinet including these oversized towers. All of the towers have an ATX compliant motherboard with Pentium 3 processors and dual SCSI hard drives. I was wondering if there was a way to take the internal hardware and switch it to a rack mountable box to free up more room. If this is true what kind of additional hardware will I need and what should I look for?
