[time-nuts] single board PCs

[gary]

You pay quite a premium for a Supermicro mobo over say an Asus, which is 
the atom D525 mobo I am using. [Supermicro didn't have one at the time.] 
The newer atoms address more RAM. But if you are going to run Matlab, 
you might want to consider the low power Xeon CPUs. Yes, that sounds 
nuts on the surface, but intel has a few Xeons that are in the new 22nm 
process, so the TDP is on par with the 40nm Atoms of a few years ago. 
Further, while they are server CPUs, consider them server-esk. For 
instance, they don't use registered (buffered) memory like most servers 
use. They can even run on non error correcting memory if you want to go 
cheap, or ECC if you want hi rel. These CPUs are used in NAS 
applications, though they are just as good as most of the consumer "I" 
series.

If you go with error correcting memory, you should get the Supermicro 
mobo. It has the hooks to report memory issues to the OS. [Linux for 
sure. I'm not sure which flavor of windows has the hooks.] Of course it 
has the IMPI also.
