Compaq Deskpro EP C266/3.2UK. * The machine has a 266 MHz Intel Celeron, 128 MB SDRAM, a 3.2 GB hard drive, 3com 10 Mbit ethernet LAN card, and is hooked up to a Compaq V75 17" CRT monitor. It runs Windows NT Workstation 4.00. The chassis of this machine is designed so that the machine can be used as a tower case (as I have it, pictured), or by removing and rotating the drive cage by 90 degrees, can be sat on its bottom like a desktop PC. You can see the rubber "feet" on the right hand side of the case.
