Just how risky is it for a noob to replace a PSU?

I really hate the idea of digging into computers and the most work I've ever done is install an extra strip of RAM (which was frightening enough). But here I am with a newly imported system and a PSU that is remarkably noisy (630W Thermaltake Berlin 80+). Sending it back for repair/replacement is not an option at the moment, so I'm considering to do it myself and get one with a better reputation and roughly the same wattage (anywhere between 620-650),

I'm a fairly careful person. I can follow guides well enough, though there's always that one step that the writer assumes is too redundant to write down, at which point I tend to get lost and spend up to an hour figuring it out.

From what I've gathered, there is no soldering required, no cutting, only some regular screws to unmount the PSU and that's about it. I read that I should touch some uncovered metal (or maybe a kitten's ear) to discharge any static electricity that has built up in my body.

Do you guys think an average person with no technical experience can do this safely, or should this be left to enthusiasts and professionals?

Update: I did it and it worked out perfectly. The new PSU is working exactly as it should. However, for anyone like me, I'd suggest to let a professional do it unless you have no other choice. I was not prepared for how strongly some of the cables were attached and especially how much force it took to get the PSU detached from my motherboard. There was definitely a risk of breaking it...

The worse that can happen is you forget to plug something back.
Replacing a PSU is one of the most easy component to replace (compared to cpu / motherboard), just remember to plug the mother board (2 plug) Hard drives / dvd and video card if needed.
If you are concerned about static. Do it on a wooden table, in a room without carpet. Also ground yourself before doing so (faucet)
I repair computers as a profession and in almost 20 years I have never seen any damage made by static and I have choked a lot of computer / hard drives etc.
