I only list the working, > 5 years old ones, mine are:
Nintendo Family Computer (or NES in the US), nearly 16 years old now, had it since 1996.
SNES, 11 years old, weird noise sometimes.
PS2, 8 years old, sent to maintainance twice, but last time I check, still work.
PS3, 5 years old.
What about yours?
