I've went and benchmarked the PC using the tools advised by SpyderTracks on a sticky somewhere, and all looks good except during Prime95's Large FFT test which threw a Hardware Failure error within 10mins of running it. Blend test sent me in a BSOD very quickly too.

A quick look within the BIOS shows that I am running XMP II with a custom DDR5 5600 profile that came already set with the computer when I received it. No visible issues using the computer normally, though I haven't played any games on it yet. Temps look good on HWInfo and MemTest passed.

Any suggestions as to why this may be?

Another odd thing... C drive is underperforming by about half as advertised whilst the other disks are within their marketed perf. Normal or abnormal?

Within the tolerance for the CPU not to throttle, which is 100c
Indeed. Which would suggest another issue? What can you think of?

Taking a look at the sloting of the SSD shortly.

EDIT: You're right, it looks like the OS drive is slotted into the second M.2 port which is gen 3 (it is numbered SSD 1 as opposed to SSD 0). Any reason why PCS might have done this? Is it worth swapping them around and can this be done now that the system is installed?

Anything logged in Windows Event Viewer after it crashes? Look for any error entries in the System logs? It might show a CPU error if cpu unstable

I'd say they decided to put the larger SSDs on Gen4, but to me it makes sense to have your boot drives on Gen4 and put one of the larger SSDs on Gen3 and have that drive to be more archive data (docs, backups, etc) where speed is not so critical

That makes sense to me too. Should I swap them around? Can this be done safely without triggering some errors?

I believe so, you might have to change the boot order in the BIOS though, but that is simple enough. Hopefully any thermal pads under the heatsinks aren't too sticky and can be prised off. You may also need to swap the standoff under the 500Gb to the new slot if PCS installed it. Generally Asus would recommend adding this if the SSD is single sided (I'm assuming the 2Tb drives are double).

Thank you for the info!

Just set the BIOS to auto as opposed to XMP and Prime95 has been running happily for over 20mins now. Will let it run overnight and report but I think it's a step in the right direction. EDIT: Prime95 has run happily overnight for over 9 hours.

Now - I would rather use the XMP profile to make use of more power in the build but I have no idea what could be causing this issue! Any suggestions?
