No SATA, still using IDE (plus the floppy controller), and the kind of honkin' big electrolytic capacitors that would always bust and leak. I'm not good at differentiating the slots, but I think it's probably PCI and AGP on there too. I can't remember what that would place it as. Maybe P3 era? P4? Definitely no later than that. I can't remember if all P2s were slot CPUs or not, but my Celeron was.
