This is a standard looking desktop PC that can be a cool little addition to your desk or any other place.

For the monitor you can use any windows 10 screenshot and size it to fit. you can use double sided tape or craft glue to stick it on.

For the speakers I printed out a picture of a speaker and cut out a little piece of it to be the speaker grill.

If you want the keyboard and mouse you can use the files from Rabbit Engineering's Mini iMac G4 model
