A coppermine at peakload won't hit more than 20W ( a C7 even lower) so the total power draw should stay lower than 30W...even disounting the inefficiency of the inverter and SMPS (Let me overestimate the losses as 50% to be on the safe side), it is still 30/0.5 =60W

Having said that, the dedicated DC-DC SMPS helps save on space and inefficiencies..Anyway, this Setup would be an ongoing effort so the Inverter solution should get me off the ground....the DC-DC SMPS can be hooked later
these are very conservative figure for a computer setup....
hdd 1-2w (which model)
wireless card 1-2w (again which model)

also the power supply adapter you showed in the pic cannot give clean continuous power at 60 watts continuously....it will heat up and will get damage....these type of adapter are made for light duty like running for few minutes like car cell phone, electric shaver type of stuff......be sure to check before going that way......
