Do you have a good working MD? How much you got under the hood?

[geekincolorado]

I have got most all the parts for my core and will now be looking at what is the cheapest a person can build an MD for.  Smaller is always better in the MD case in our house.   If it can't be seen and can do its task then that is best.  Would like to hear from those booting via netboot (pxe) and those that are using local boots (hard drive).  Please post with costs and what you think of your system.
