@Jack Yeah I actually edited my answer after that, cause it turns out I didn't read well enough, and his brother already has an SSD! I just made recommendations for if he wanted to spend the full amount, but like I said, for £830 it's already amazing so he doesn't really need to.
@Nikolay Savov If you want silence (which is great, I love silence) you still don't need to spend anywhere near as much on the setup. I question some of your choices as well, since they don't really seem to be optimized for "silence". The Corsair SP120s for example, are known to be very noisy fans. The H100i is not quiet at all, as shown by
this review. 45 dB vs. the 28 dB of the Noctua, that is a
MASSIVE difference in noise, since it's logarithmic. Not only is your power supply a bad unit quality wise, it's again
very loud! I suspect your intentions are good, but you've put together a terrible build, which is way over budget, that isn't even quiet at all, and has a dodgy power supply.
What would the OP gain from spending $350 on an Asus Maximus, vs. $125 on a Gigabyte-U3DH? How do you justify that extra $225, which could be used on a better video card? I basically ask myself this question about every part of your build, why $180 RAM, when there are better, $100 kits available? It really makes very little sense.
Finally, about the fact that your build is from US stores, you say he can just look on UK sites, why not just make/link your build on the UK version of PCPartPicker instead: http://uk.pcpartpicker.com/ This hints that haven't read the original post to know the requirements of the build, or you don't care enough about giving the OP a decent build to link it in a form that's actually useful to him. You don't even have to remake the build, you can just transfer it from one form to the other...
