Suggestions for laptop or mini pc? (Australia)

@Prokristanator  If you want a laptop, your questions become much easier because there are many fewer options.  If you're willing to get a desktop though, it's the better overall choice.  You'll see better performance for the same price and have much more flexibility in every aspect, including for future upgrades, whether you do them yourself or ask a friend to help.  I can look for laptops if you want, but I think you'll be happier overall with what you'd get out of a similarly-priced desktop.

And yes, it sounds like a Windows PC is the better option for you.  While new Macs can run many Windows applications with Crossover, they do lose some performance in the process, and Crossover doesn't work with everything you might want to use.

As far as a desktop goes, let's start with the easy part first.  You'll plug your monitor directly into the graphics card, and any modern graphics card will have both HDMI and (full-size) DisplayPort.  How many of each can vary from one card to another, but both Nvidia and AMD impose standards that include these ports.

For the graphics card itself, a 1650 (any flavor) is the lowest you'd want to go, at least as far as Sims 4 is concerned, and the 30-series Nvidia cards are unfortunately still quite expensive.  You might be able to get a custom build with a 1660 (any flavor) or perhaps a 2060 for a reasonable price though; I'd have to check the various sites.

It sounds like you want at least 500 GB SSD storage, and you should be able to find that (or more) for a reasonable price.  Don't overthink this or the RAM decision: components from a reputable company should be fine.

If you want quiet fans, you may need to either get a custom build or replace the existing fans, which is like playing with Legos that need to be plugged in.  (So not difficult or complicated but requiring some attention to detail.)  Whichever path you choose, you'll want a case with more fans rather than fewer, or at least more slots for fans: the more fans there are, the less the workload each one has, and therefore the lower the speed they need to run.  You can also adjust fan speed with software, so the fact that your computer comes with fans running at max doesn't mean you have to live with that noise.

The bottom line is, choose a desktop with a case with a lot of room for fans and go from there.  If you did order a custom build, you could add extra fans, or quieter fans, for a small price increase.  I can help with this if you want, but you should be able to see just from the images if not from the product descriptions.  This is a very good reason not to buy a prebuilt computer from a company like Dell or HP—the cases they use tend to have poor airflow and just a couple of fans working much harder than they should.  There isn't anything you can do with that setup either, since the cases don't have extra mounting space.

As an example, I priced out a build on Centre just to see what I'd get:

• Processor:  i5-10400F ($209)
• Motherboard:  Gigabyte B560M DS3H ($99)
• RAM:  G.Skill Ripjaws V 2x 8GB ($135)
• Storage:  Crucial P1 500GB ($66)
• Case:  (I didn't pick; that's a personal decision)
• Power supply:  Corsair CV550 550W 80+ Bronze ($72)
• Assembly labor:  ($110)
• CPU cooler:  Noctua 120mm NF-F12 ($55)
• Graphics card:  Gigabyte GeForce 1660 OC (629)
• Total:  $1,375

That's not a bad price, even once you add in a case and some extra fans if you want them, but it's worth comparing with other sites.  In particular, the graphics card price is highly inflated because of the current market, but that doesn't mean all stores inflate all models' prices equally.  And of course it's easy to swap out components as you like.

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