Others have already explained this but yes, it does have 5 pci slots

(here I go again.... :-)  Yeah - I did do a tool that will draw almost
the tree almost exactly the way you drew it.  The tool is called
prtconf (name stolen from elsewhere ;-) and is bundled with the abc
stuff I put out for comment - you don't even need a hacked libcurses
for prtconf.  I would love to see what it does on Justin's monster
machine :-)

I don't think anyone argues about that one.
