Short steps. Not complete or conclusive.
After you get your stuff. Take a deep breath! It's here. Take out all your parts from the box and FIRST....put the newegg UPS box and all the other stuff somewhere and out of the way. And then place all your parts in a place.
Start with the case. Open it up and take off any plastics or styrofoam or anything and then lay it flat on the ground with the case side open so you can look in. Take a look and determine what you should do from here. Some cases require you to put your PSU in first. This could be due to room or DUE TO CABLE MANAGEMENT. Look at the routing slots. Make a mental note of where and how you will route your cables.
Take the bag of screws and standoffs from the case and place it somewhere.
Then go to your motherboard. Pull it out. Do whatever you want to oogle it for a minute or read the box and go 
.
Ground yourself. Then take it out of it's anti static package and lay it on it's anti static package while you take out all the other mobo stuff.
Now go to the case. Take the brass standoffs out and have it on hand. Slowly take your motherboard and lower it in CORRECTLY so the perephrial side matches the case(you don't need the perephrial sheild yet). Now make a mental note. You then need to raise your mobo and slowly put the brass standoffs in the case by the holes on the mobo. Some cases have markings that tell you which one is the ATX hole and which one is for micro ATX or others but some don't. I dont' remember if this did. Anyway, after you do this and get all the standoffs snuggly in place make a mental thought. DO YOU need to put the PSU in first? The answer 80% of the time should be no. So then lower your mobo in and see if it fits and all the holes match. Does it? Yes. then take the mobo out and put on the wrap again and take the perrephiral shield out and attach it to the case's perephrial hole
. 
Then take the mobo and put it in and make sure all the stuff fits through the perephrial shield and then screw it in place. You may have to push it towards the shield as teh shield may have metal prongs that push the mobo back a bit and so you need to apply some pressure to put it snuggly into the holes while screwwing it in.
Then read the manual and see how to connect the case buttons to the mobo pins.
After that you instal your CPU following instructions
Then you instal your RAM. Sometimes CPU heatsinks can block RAM but in your build it won't. Placing the two RAM sticks side by side next to each other in the same slot color or dimm series is usually recommended but if your computer won't post put it in a Dimm A1 Dimm B1 config.
Then you instal your HDD into the slotless thing. May take a few minutes to see how it works. Then do your ASUS drive.
Instal your PSU. Then take out cables will be needed and plug it into PSU and start routing. Take the back panel off the case on the other side and start routing. DO NOT PLUG YOUR PSU WIRE IN YET!. The one that attaches to your house plugs.
Then instal your GPU. Depending on what you did, a wire may get in the way of which you may have to take out some wires to make it fit or anything or do the GPU first and then PSU. Whatever works. Remember the GPU has two power slots you have to fill. Route your cables.
Do a final check that your CPU fan is plugged in. All the fans are plugged in, hard drive and any drives are plugged into SATA and also has a power cord(need both). Make sure your main power AND 4 PIN CPU POWER. Are both plugged in along with anything else. Do a survey of how many connectors you have left and room for further upgrade.
Do some more checks.
And then plug the power cable in and boot. If it doesn't boot come back and ask us.
If it does. press the button to access your bios and set first read or boot to your DVD drive first and THEN your HDD. Disable anything else as having floppy selected can slow times. Open up your DVd drive. Pop windows in. And then restart your computer. Just press the power button or the pwer switch. This may take multiple trials to set yourr computer UEFI settings(almost said BIOS) and popping the disk in.
Then wait for Windows to instal!
