Im using Inventor 2013 (lol) but create a plane on that side you want to mirror. Enter sketch mode and select the lines you want to reflect using the mirror tool. Finish sketch and extrude.
If you already know what parts you want, you can build a part list yourself on pcpartpicker.com. Just find a case you like and maybe a H100i if you want water-cooling.
No because nobody gives a shit about binary or how a CPU is made, people just want tech to work. OP can still make a good pres and teach his classmates something new.
You're missing my point. Just because OP loves Comp Sci and technology doesn't mean he should make his classmates suffer through a presentation over topics they have no knowledge of. You're acting like you look down on non tech-savvy people simply because they have different interests. I'm saying OP needs to select a relatable topic that can engage his classmates and make a good presentation.
