NAS boot issue
One of the lads at work gave me his old, 8 year old NAS, I took it home booted, configured etc and it's been working fine as cold storage. The other week I come downstairs to see it's turned off, t...

If you are using XRAID, any data is striped across all 5 drives. Even if you had all 5 drives connected to the PC, you would not be able to access the files in Windows (or macOS) because neither operating system supports the ext file system used in your legacy NAS.

It is possible that the power supply has failed. What happens when you boot it up with no disks? Maybe also check the no-disk status with RAIDar while the system is running. https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar

FWIW, you should always have a backup of data you care about (even with cloud storage).
You'd need to be able to connect at least 4 of the five disks to recover data. Once you've accomplished that, there are RAID recovery software packages you can use. One is R-Linux. https://www.r-studio.com/RAID_Recovery_Presentation.shtml
If it is the power supply, which is high on the list of probable causes, it's fairly easy to connect a standard ATXV12 supply to the NAS externally in place of the internal one and run it with that to recover the data. That's actually also the easiest way to determine if it is the supply that's the issue.
Since you will be running it that way for a bit, you should block the internal power supply fan exhaust hole and any gaps created to allow the power cables to come out. Masking tape works fine. The remaining internal fan will then properly cool your drives.

So any standard PSU that I can pull out of a dead PC in our graveyard at work should work? I literally need it to run for 2 or 3 hours so although cooling would be ideal, probably not the end of the world if I can't get a good seal.

So this is the first NAS I've actually ever used so I just went with all the deault settings but XRAID sounds familiar...I'm starting to think it might be the PSU, annoyingly the only way I can really test that theory is by plugging it in and pressing the power button, there is no change booting with no disks, clutching at straws I removed the CMOS battery, didn't do anything.
I don't really have a way to connect 4 disks, I'm going to need to think of something else.

If you have an ATX supply or can borrow one, you can jury-rig an extension cable to connect it to the NAS. That would let you test it, and if it works you can boot and off-load data.
The cabling isn't quite standard, you will need to make a mod to the extension cable if you go this route.
Actually the PSU for a 6-bay legacy system has completely standard ATX12V (24 pin main) connections. It does need 3 4-pin Molex connectors, which newer supplies may not have, so you might need a Y cable or SATA to Molex converter to get enough. There is also normally no extender needed. If you decide to go all the way to replacing it with an SFX format supply (which is what fits in it internally), you'll need a 24-pin extender.
The 4-bay units are the ones with a non-standard connection.
