I do not want to dissuade you from this endeavor.  But, if you are only 
interested in learning
about z/OS, you might consider the path outlined in the link below.  
Specifically, the Personal
Edition.  

https://www.ibm.com/docs/en/zdt/12.0.5?topic=overview

This is the official IBM mainframe emulator, that runs on Intel based systems, 
under Linux. 
Other members of this list have signed up for zD&T PE.  Although, at the 
current time, IBM 
has not delivered all of the necessary components.  Word from IBM is they are 
working on
it.  Also, I think this environment is only for running z/OS, not z/VM or z/VSE.

Lastly, if you interested in zLinux, you can run that on a Wintel platform 
using the Open Source
mainframe emulator Hercules.

Thank you for the input. Would you know where to look for ckd devices? I have 
seen parts of a DS6800, but always without the controller. I know luminex and 
IBM also make smaller rack mount units, but I haven't seen any of those either.

Basically, running FBA storage restricts you to running z/VM and z/VSE, and 
possibly z/Linux (I've never run it on FBA, but there's no particular reason it 
wouldn't work). z/OS requires CKD DASD.

Learning experience? Absolutely!

I want to get a z/Series myself, but there's a tradeoff there...in particular, 
I don't think I could manage 3-phase power.
