I hope that video walkthrough was helpful
Two weeks is plenty of time to do a little light homework on building. All you really need is a philips head screwdriver, magnetic is handy to keep the screws on the tip

Some cases are tooless by design, so all you really need do is screw down the mobo. It's hard to say exactly how long it would take you but you probably are looking at a couple of days/weekend. Not just to do the build but get the OS on and do updates, install the software\games you want etc. Even a prebuild would need a little tinkering to get it how you want it.
People will suggest anti-static wriststraps but I've never used one in well over a decade and never had any problems. Ground yourself before you touch the components either on the case or a radiator in the house.
The offers here change weekly (on the wed), apart from the today only offers obviously. So my spec above might not be the best bang for buck for when you are able to buy. Any more questions fire away, when you are ready to buy we can have another crack at doing a spec taking the offers into account
