Hot IBM Test Ride

From Fat Wallet:
IBM offers a free test drive for 30 days of Linux running on the IBM eServer zSeries 64-bit mainframe. That's the world's largest and most powerful Linux server.

Choose from Red Hat 7.2, Red Hat Enterprise AS 3, or SuSE SLES 8 distributions for zSeries. You'll get your own z/VM (virtual machine) running 64-bit Linux, with root ID, 1 GB of disk space (mounted at /opt), and remote access via SSH/SFTP/SCP. Open to "those who are curious about the Linux for zSeries environment," and extremely helpful if you have some Linux software you'd like to test and/or compile on the IBM zSeries mainframe.

IBM does not provide technical support for this free service. Fee-based services are available if you require more.

This is a fantastic deal if you're curious about Linux, if your company has a lot of servers (30+) and is considering reducing that down to a single mainframe to save money, for testing your application on IBM mainframe Linux, for getting experience working with zSeries Linux (it isn't any different, actually), etc.

No expiration date, but offer may end at any time. For the record, I work for IBM but am not affiliated with this particular group. And considering the vastness that is IBM (over 300,000 employees), hopefully I'm still within FatWallet guidelines. Obviously IBM does not make money on this offer nor do I.
