Hi i have around £200-£250 ($250-$300) to spend on getting a motherboard, CPU, ram and maybe a PSU so the systems will at least be semi usable allowing for as much upgrade-ability as possible as this will also be going on a wall case-less or in a custom made Lego case with custom water cooling over the next year. Even if this system first boots to 2gb of ram for the first month is fine, so any recommendations will be grateful. PS i live in the UK
