First and foremost, I don't know which motherboard to buy I have a budget of 100usd and below. I have already decided to buy intel i5-4690K for my cpu and XFX radeon R9 390 for my gpu. Secondly which PSU should I need to buy? Lastly I am using a cardboard as a case, the reason is using a cardboard have more customizability and it is cheap as I do not want to spend money on cases. But I have a major problem, how do I create a power button so that I can click to start up the system as cardboard do not come with a power button. Second reason I am using a cardboard because I want to laser cut my own design and how cool would that be? Please help as this is my first time building. Thank you in advance!
