havent been on for a while, so had forgotten all about this doh!. thank you for the replies.
things have changed a bit since i made this thread. so the cube case i was going to use is now sporting my dell xps specs, well obviously with a compatible mobo and a different psu as ive modded the case somewhat. i havent been pc gaming, so no need to build for that anymore(never sold my laptop anyways), but i am doing a custom DIY build in a not so known chassis of an idea(record player) which limits me to mini everything depending on psu used which i have been trying different style units, however i have seen a 160w pico on the bay likely used as its under 15 quid which im itching to buy.
because of the nature of that custom build i will be looking at APU or least non discreet graphic options for the time being as im not sure how gaming capable id be able to make it, so spending big isnt a route i will want to take. its good to know what i could power though.
