battery powered mini itx

[riskinhos]

how can I power a mini itx motherboard via rechargeable batteries just like a notebook? what would be the best battery type and what components would I need?
thank you

Use a picoPSU-90 for generating the board's voltages. Use a 12V lead accumulator to provide the primary power to the picoPSU.

thank you so much for the help. But I need something more portable. with lipo or nimh how could I make this work like a notebook?
would something like this work? http://www.ebay.com/itm/23000mAh-5V...34723?pt=Battery_Chargers&hash=item232daaf823
how could I select the 12V? could I charge the battery and have it power the picopsu at the same time? is there any way to monitor the battery charge in %?
once again thank you so much.
