I don't have it running it on PC hardware directly, but I've managed to install the latest OS X Mavericks on a Windows 8.1 Dell laptop in a VMWare v10 environment. I've only had it running for a couple of weeks, but it seems to work really well. I'm pretty new to OSX, but have been able to install a few program's (including MS Office & Adobe CC) without any issues. I've also been able to copy the VM onto several other desktop and laptop PCs that are running VMWare and got it running on that hardware too.

There's a small patch that needs to be applied to the VMWare program, which then allows you to select Apple OSX as an operating system. This patch came with the copy of OSX which I acquired. You should be able to find both on the usual torrent sites.
