This is a very open question: I have a spare screen, speakers, and a cheap steering wheel and I was thinking of rolling them into a little racing car sim for my son (he's turning three in July). My main contribution would be jigsawing and painting and gluing together a little seat / desk in the shape of a racing car. My main obstacle at the moment is what to put in it. There are a lot of options. They all need to be able to support the Thrustmaster Ferrari GT Experience, and provide DVI or VGA input to the monitor.
2. I could spend some money:
2a. A FM2 board and a Richland APU (Linux open source support for graphics on Richland is working pretty well). I thought it would be fun to have a tower cooler like a CoolerMaster Hyper 212 emerging from the hood.
2b. I could get an old Playstation (2?3?) or Xbox 360.
2c. I have an Athlon 245, Ram, a spare HDD and an nvidia GT210, and a spare Windows 8 license sitting in boxes. An old AM3 board and a case and PSU would be an alternative to a new FM2 board.
2d. Something else?
So I thought I would consult the great council of chiefs: any thoughts?
Option 2C will run RFactor (rev 1) well enough if you limit the filtering. Anisotropic is admittedly handy for a race sim, given the foreshortened road textures. The GT210's anemic memory bandwidth will probably limit any filtering to a bare minimum. That said, I doubt a 3 year old would notice.

RFactor has hundreds of cars, and hundreds of tracks, the vast majority of which are free mods. For $28 you can't go too far wrong.
The only caveat is that you may need to dig into ini files to tweak the controller, and may need to shuffle directories to install some tracks. None of this is too daunting, but the program environment isn't as 'one click' user friendly as it might be. The program will make full, proper use of dang near any controller on the market.
