I too have old macs that cant be updated. I just keep a time machine backup and if ever I get hacked a quick restore will fix. For 10 years I've had no issues !! 
Except for apple silly's (sic) there is little to worry about (ring 0 et al). I expect Bad Guys would put their efforts into modern exploits not ones from 'olden days'.
My only issue with perfectly functioning iMacs is that my wife want's lightroom. and  photoshop (which demand the 'latest' os)  whereas I prefer gimp.
At least thee and me are free of apple's incessant nagging :-) BTW if you are not using flash do your self a mighty favour (mac fancontrol)
Another point if anyone reading wants opinion: (How it pains me to not say VirtualBox!) running a VM under parallels is probably nicer than native hardware for linux (pad gestures and touch-feel, bluetooth, heat come to mind) and speed is quite excellant eg M2 speed is 1800 MB/s on my macbook)
