@It's ANGRY MUFFIN time!!! That copy of Windows is costing you £110.35 which is quite a waste. You can pickup an OEM key on eBay here for like £3 and it works just fine.
as from an experience, I live in Israel aswell and i think the ram is too much for myself when i had to do a pc build, I bought the ram and the cooler from amazon , way more cheap
