It’s fine, the repacks generally tick up the CPU and RAM a lot. It’s just extracting things faster than if it didn’t use that many resources. You only really have to worry if the extraction process halts for unreasonably long (over an hour or smth), then you may have a system issue (not the repack’s fault).
As mentioned before, disks are great for archiving files for long-term storage, so they eould work for that. You could also see if you have any non-techie freinds who want/need a cd or two burned (though not likely, still possible).Alternatively there are quite a few crafts you could try.
