More stuff we don't need no mo'...
Asante FriendlyNet GX4 Model 400 4-port Gigabit (1000 Base-T) Ethernet Switch
6 months old, likely still have the box (no promises)
Specs are here or in PDF format here.
this unit retails for around $1150, lookin' to sell it for $700 or thereabouts, including shipping of course. Of course this is a VERY fast switch that'll work with any newer (Gigabit) G4 desktop.
