The first Mac I ever 'owned' was a PowerBook 100 I purchased for £100 second hand in 1998. But prior to that I had cut my teeth at high school on:
Mac Classic
Mac LC
Mac LCII
Mac LCIII
Performa 475
PowerMac 7200
Then when I was at Uni, I bought and sold quite a few machines to make some money on the side... including.
A PowerBook 145b
PowerMac 8500 -- eventually with a G3 upgrade card.
PowerMac 6100
PowerWave 604/120 (Yes, an old Clone!)
PowerMac 7600
Macintosh IIci
Macintosh IIcx
Performa 200
Quadra 610 (with PC card)
Performa 575
Power Mac 7100...
The list goes on.
Today, my 'fleet' includes.
Two Mac Pro 2,1 from 2006/07. Both are upgraded with new graphics cards, bucketloads of RAM. Both run Yosemite.
G4 Mac Mini
Intel Mac Mini (first gen) upgraded with Core2Duo
G3 Pismo Powerbook.
3x PowerBook 5300 in various guises (I love this 'road mac' but I'm trying to make a decent one out of the worst mac ever made)
Apple ][e.
G4 Cube
MacBook Pro Retina (first gen) 15 inch
MacBook Pro Retina (2013) 15 inch.
MacBook Pro (2006, CoreDuo) 15 inch.
