Elliot's Mac died and now he has to use an old Windows machine. What can he do to speed it up? Leo says that Elliot is the prime candidate for a Raspberry Pi 2 computer. At $35, he can't beat it. And it runs on Linux.
Elliot wants to game, though, and he plays Gary's Mod a lot. There is also Steam for Linux, but he might not be able to get Gary's Mod on that. If he needs a decent computer, it all comes down to budget. Leo says he can also put Windows 10 on a Raspberry Pi, but it won't be very good with graphics.
The Steam Box may be a good option for Elliot if all he wants is a low cost gaming rig. Fry's has a PC for under $100 with 2 GB of RAM. But Leo says that Elliot is going to end up spending about $500 for a decent gaming rig. And if he builds it, he'll learn how computers work. It won't save any money, but it'll be a great project.
Leo suggests checking out pcper.com's Hardware Leaderboard. They have the best components for each price level. He should also check out NewEgg.com's barebones systems.
