never really liked apple, even as a kid it was mediocore experience compared to pc.

I dunno maybe if you got something to shoot at it, its worth buying.

The last pre-trashcan model would have been a "MacPro 5,1" refreshed in 2012. The high-end CPU option was dual Xeon E5645s, which are more-or-less equivalent to a power-limited Core i7-970/980. I don't remember this generation being known for efficiency, although that always depends on your workload and what you're comparing it to.

The 2012 model is the last tower MacPro. I still have 2 of them and no they are not very efficient by today's standards. They are also pretty much broken at this point for current macOS releases via OpenCORE Legacy Patcher and you'll also likely need to get a BIOS flashed GPU to support getting even a somewhat recent version of macOS installed without it being a slideshow.

IMO it surely is not worth the effort. As for playing games on them; don't bother there is hardly anything that plays well on them even with all of the ports from aspire.

G4 and G6 Mac Pro I believe they were called. They were nice cases though with exceptionally good airflow

G4 was the PowerPC MacPro and is way old. The "cheese grater" models were not G4s. The original ones were G5 power PC just before the transition to Intel. The last were the MacPro 5,1 in 2012

G5 yea that's the one. Yes that was still Power PC before Apple switched to Intel CPUs for a while

IIRC the G5 was as good as having dual Pentium 3 or dual Pentium 4 CPUs at the time of release

Yeah, "PowerPC" as a brand practically ceased to exist after "G5", although they kept using variations of older cores in embedded processors. IBM is arguably still carrying the torch of the original "AIM alliance", but I guess it's mostly propped up by government-sponsored supercomputer contracts these days.
