You could install Ubuntu. Or other Linux Distros like what Kevin said. But they may sometimes not come with .exe support. And they may not be able to run a lot of the games that are out there.

On a pc you can install almost anything .
Two of the most popular ones are Linux and Mac(A.K.A)Hackintosh.
However there is ton of exciting alternative's out there. Here are just a few.
(1) FreeDos http://www.freedos.org/
Basically this Operating System is a clone of the Old Dos that Microsoft used.
However whats nice about FreeDos is that it can be used in your own stuff. Because it is not owned by Microsoft and is completely open source.
So you can make a app that runs in dos and then distribute it with FreeDos. I love it and plan in the future to make my own custom software to run on top of FreeDos.
(2) ReactOS http://www.reactos.org/en/index.html
This Operating System is meant to copy the functionality of Windows Xp from the hardware level to software level. Its still in alpha currently . So not recommended for everyday use. But it works closely with the wine project for Linux.
Basically it will run windows software like it was running natively on a windows system. In order to make the operating sysytem they had to look at Microsoft Documents on windows api and made their program based on that.
Quite amazing for a open source project =D
(3) BareMetal OS http://www.returninfinity.com/baremetal.html
If you want to do High Performance Stuff with your computer this is the way to go . The Operating system only takes up 16K so its extremly small. Very Good if you know how to program in assembly .
(4) FreeNas http://freenas.org/FreeNAS
This one is onother of my favorites . If you have a older computer sitting around that connects via ethernet. You can install FreeNas on the box and then put a bunch of harddrives inside and attach usb harddrives outside . Then it will work as a server for your network where you can backup files to =D .
(5) Minix 3 http://www.minix3.org/
Finally Last but not least Minix. Minix is a very small os that acutally has a GUI(Graphical User Interface) Unlike Baremetal. But still manages a very small and stable Operating System =D
Hope this helps.Having fun playing around. There are tons of other Os's out there. These are just a few that i like =D
