Looks like a neat build
The Asus mobo comes with 2 SATA cables so if you've ordered them as well at least you'll have a couple of spares

cool, didnt realise so yes, 2 spare cables for me

nice build giving me food for thought, my laptop is now deceased due to an accident with milk and rice krispies So had to resurrect my ancient Athlon XP3000 and NV6800 AGP gfx Need something better faster quieter !

you lucky, the ratings are hideous on newegg for all large capacity green models. I was almost tempted but decided against it. Obviously I dont just check one src, in datacentre usage I have also seen bad failure rates.

500 watt is plenty assuming you not going to buy a monster gfx setup.

psu's get less efficient as well as less reliable the closer they run to rated wattage, so even tho you could get away with 400 watt, should stick to 500watt+.
