Considering your location, Matty, there should be some Tech-Forums members in your area (Birmingham, UK). One of them may be willing to give you a hand with the actual assembly.
Haha, I love the hospitality in here, I feel like I should be putting on an open bar for you guys, . I should be fine with the build, I've thrown together a few computers before now, albeit a good while ago. It's just my "up-to-date" knowledge that sucks, hence I need a little help with the quotes and component picking, the likes. That would be a great offer though Trotter, especially if I did end up buggered somewhere along the line, !
