You could do this + this. If you've only got 2 fans, then the one you linked + the power supply I linked would work.
Well, usb 1.0 and 2.0 deliver max 500mA, and usb 3.0 delivers max 900mA. A quick google gives us 100-200mA for a fan, but thats at 12v. 12 times 150mA is 1.8 watts. Usb 2.0 can deliver 2.5 watts, so it wouldnt hurt the pc, it just wouldnt work. Id say go for a 12v wall adapter. Its the least likely to give you problems. Just not the one you posted, unless you want to solder the fans leads onto it. Go for something like this. Hope this overly long explenation helps 👌
On a quick glance, I seem to recall DC adapters and such. Something like this: https://www.amazon.com/NOYITO-Adapter-Connector-External-100-240V/dp/B071V9CQ5H. Pluggin a case fan in directly would cause the rfans to run at full speed. You could also plug them all into a fan controller hub inbetween the power and the fans, thereby keeping things quiet. You can straighten up the wires and do a bit of cable management, and it could still look nice and such. Anyways, it sounds like it could end up being another design as an add-on.
This will allow your PSU to turn on without a mobo.

A lesser known but significant issue is that you don't want to mix and match cables from different power supply brands and sometimes even different power supplies of the same brand, it could possibly fry your HDD. These cables can be tough to find and order separately, so I just use a power splitter extension instead.

Some other things below for fans that I used for mine, but you might already have stuff laying around. You'll also need a molex to 4 pin or you could opt for a fan power supply to wall outlet, only if you don't overload the 2A.

You'll also need to buy 2x SSFF port for the R5 box and your main, plus extra SFF-8088 cables (1m-2m length), this starts $$$ adding up fast unless you can place both devices very close and snake the SFF-8087 forward breakout cables through the R5 case then through the main system case to the HBA unless you have a card with external 8087s. I haven't seen any SFF-8087 forward breakout cables longer than 3.3ft though and you'll probably have these both connected internally so these boxes will have to be right next to each other...

I didnt search extensively, but I did see a SFF-8088 to sata 6ft cable, but it had no reviews and the title showed 8087(maybe so it gets noticed on search results), but the description was correct as 8088. Depending on your card then this might be an option. This is where nas boxes come in with network connections for farther distances or you invest in all these cables and adaptors so it doesn't look janky with cables snaking in and out of the cases.
