hmm.. 24/7/365 since 93' or so to now.. This A4000 has only been off for repairs or upgrades. It started life as a 040/25mhz A3640,but i got it with a warpengine 040/40 and the piv came around 96' i think , and then a cyberstorm MK2 060,then cyberstorm PPC..ironically all this ran just fine all these years with the stock psu(it still works today!) and i didn't lose a psu until i put this in a elbox tower and mediator.The cheap atx psu died 6 months later and i have put a total of 3 in it since its been towered.it still runs everyday and is in use.current config is cyberstorm ppc 060/60 604e/233 128M ram,Mediator with voodoo 4 4500,sb128,tv card,deneb USB,100Mbit ethernet,fastlane z3 with 128M ram,and i use a 32GIG kingston CF as a system drive via the cyberstorm ppc scsi and acard UWscsi->ide bridge and a 500GB ide hd as a storage drive,dvd burner,also on the UWscsi.I think i paid $1000 (seemed like a million dollars at the time :)for this machine with the warp engine in 93 from a friend and seem to have gotten my moneys worth.Takes a lickin' and keeps on ticking
