Yep, the M2-ATX, at 160W would be more than capable of running that system.
I have had, for the past 2 years a M2-ATX powering a little Industrial Project of mine, with a Commell LV-677, 2.13gig CPU, 7200rpm drive et al. Did so without a hickup.
Nice cases, those Sereners, I have a GS-L05 that I'm converting to a fully passive-cooled setup, with custom heatpipes from Coolermaster Netherlands store, and my other little setup, my Commell LS-373.
I will have a new, much beefier top to allow cooling both the NB and CPU passively, as I simply cannot justify getting a new GS-L10
keep us posted though, interesting project in the making here!
