Fair enough on the builds, they're just suggestions after all.
So here's a few pointers on actually assembling the system:
It's not that hard to actually assemble a PC, there's loads of YouTube videos to help, so take a look at a few to give yourself an idea as to what is required, but apart from installing the CPU and its cooler the general procedure is much the same for Intel or AMD.
1: Read the manuals first and understand them.
2: Proceed with one part at a time and don't rush.
3: By doing #1 and #2 you'll kill 90% of the problems most first time builders encounter and get that lovely, fuzzy feeling when the system boots up first push of the button.
4: Use a GOOD QUALITY magnetic screwdriver, cheap 'drivers can damage the screwheads and are more likely to slip out as a result, which can easily wreck a motherboard.
5: Some CPU coolers have a sticker covering the base don't forget to remove it prior to installation it's obvious enough if it's there. 😉
6: Installing the motherboard is the most risky operation, and best done with the CPU and cooler already installed, that way you can use the cooler to gain little more control over the motherboard.
Lower it in at an angle so the rear connectors pass through the sprung steel EM shield first, then push it firmly towards the rear of the case and lower it into position.
Almost certainly you'll need to apply a little pressure, pushing the motherboard towards the case rear and against the EM shield springs in order to get the mounting screws in.
Get all the screws in and started by a turn or two THEN tighten them.
7: Most cases still use tiny little connectors for the front panel switches and LEDs, use tweezers here.
8: That big 24 pin motherboard connector is always hard to get in, lubricate it with a little petroleum jelly before trying to get it in and if the socket isn't well supported, carefully support the motherboard by using your fingertips.
9: DON'T PANIC! If the system doesn't start first time it's entirely likely you've just misconnected-or not connected-a cable.
Check through the motherboard manual and make sure all the cables are correctly connected, the memory module/s are fully seated, the CPU cooler fan is connected to the correct motherboard fan header and the graphics card power lead/s ( if required) are plugged in.
