can an hp 22 all in one run the sims 4

@sachaha  Of course you can have a white computer case if that's what you want; the only issue is the limited options relative to black and gray cases.  This desktop is significantly more expensive than the one I linked, but it's also significantly more powerful, in fact it's overkill for Sims 4:

This is more on the low end for a gaming desktop, but it should still handle ultra graphics settings just fine.  I'd prefer something a bit more powerful in your shoes, but if all you want to do is play Sims 4 and maybe a few less-demanding games, it's a reasonable option:

I don't really know anything about the reputation of stores in New Zealand, but if you trust this seller, these are all good options, listed from weakest (equivalent to the system I linked yesterday) to strongest (about as good as the first one above):

There's also this option, which comes in several colors, including white.  Its processor is not as good as the last one above, although it's still fine for Sims 4.  All else being equal, I'd go for the one above or the first one I listed, but maybe this one is more convenient for you:

Again, all of these should have no trouble running Sims 4 on ultra settings; the question is how much extra power you want, if any, and how much you're willing to spend to get it.

If you have more questions, please feel free to ask.
