The GPU was around £100, the RAM was about £27 and the PSU made it up to £385 total. Could someone please suggest equal parts at the mentioned prices. I would like the total price to be around £400.

Thank you to everyone in advance

This is as close as I get could get it to your original pricing. Don't worry about the Ram speed, you board only runs 2133 anyway.

Don't worry about it not being able to verify the size with your case, I checked the case's website and it fits up to 320mm graphics cards. Hope this all works for you, good news is the r7 370 is faster than the r9 270X! (not by much). Best of luck building your PC!
