... and I would like some help deciding which parts to put into it. 🤣

Anyhow, I have this old 200-round 7.62mm ammo box that I've been thinking of doing something with for a long time, and then the idea hit me "what if I built a computer into this?"

I'm thinking of going with a Mini-ITX board based around the LGA1155 or Socket FM2 architecture, 4-8GB of DDR3, a 160 watt PicoPSU, and a 250GB laptop hard drive (or a decently-sized SSD if I can get one for a good price). I'm forgoing adding an internal optical drive, since I don't use them that often and adding one wouldn't work well with my space/power/cooling constraints, and I'm also forgoing using a normal GPU (shocking!) for the same reasons.

The main thing I'm wondering is, what would give me better onboard graphics, Intel's HD 4000 offered on some of their Ivy Bridge CPUs, or AMD's Radeon HD 7540/7480 offered on their 65w APUs? As well, which one would have lower cooling requirements? Since I'm not much into newer PC games, the most I will probably be playing on this is TF2, the Dolphin Wii/Gamecube emulator, or Carmageddon through DosBox (though that really depends a lot more on CPU power than GPU power 🤣).
