CPU main PCB is a standard EPIA
ROMs    epia BIOS + solid state HD

1x VIA EPIA5000EAG (main PCB) with:
VT8231 South Bridge
VIA Eden Processor
VIA EPIA Companion Chip VT1612A (Audio CODEC)
VIA EPIA Companion Chip VT6103 (Networking)
processor speed is 533MHz <- likely to be a Celeron or a Pentium III class CPU -AS

 it's a 2002 era PC at least based on the BIOS,
  almost certainly newer than the standard 'PENTIUM' CPU
