Could anyone answer a couple of question about a Predator Orion 3000 PO3-620 ?

Model Name: PO3-620

Part Number: DG.E21EK.00D

1. It seems to be one of the most affordable ones with a RTX 3070 and I can't find anywhere that version/maker of this GPU they use.

2. Almost everyone reports 80+ Celcius under stress/gaming and I'm not comfortable with that. It will be used for work (nothing to intense) for 9 hours and then a few hours of gaming every day.

At the moment I have an i5 that doesn't go past 65Celcius with a £30 cooler so I'd obviously like to change the cooler in this PC if I buy it. I've seen a few threads here about this issue. How hard is it to change the cooler in this case ?

3. What motherboard is used for this build ? I'm curious if the RAM can be upgraded past 2400Mhz.

80+C is normal for heavy gaming use on most every gaming PC. That's where they are designed to run. When used for normal stuff they drop down into the same range as regular PCs, 30-50C, I'm running this laptop at 50-60C or so right now on all cores. Cooler change difficulty depends on the cooler you get. Most have their own mounting brackets and require a motherboard pull to get the stock bracket out. The motherboard is a modified DTX form factor, with a 'diving board' out the front to bring the ports forward without cables. It's one of the new style boards that uses the ATX12VO standard for power, #2 & #7 are the power connectors.
