Yeah, check the tonymac guides.
I used the iBoot method with a retail Snow Leopard disc and got it up and running, then downloaded Mavericks through the app store and installed that using it as a bootable USB drive.
I've got windows 7 on my SSD, and OSX on my other 500gb hard drive. The only slightly annoying thing is that I have to take the side of my case off and swap the power/sata cables in order to boot from the correct drive.
I realise I could just select which one to boot from in the BIOS but I'm a bit apprehensive about booting into an W7/OSX with both drives connected and on. (Heard that It could mess with thing, don't want to risk it just yet)
Good luck with yours
