i'd suggest a little more on the mobo...you can get this one
Newegg.com - ASUS P5Q SE LGA 775 Intel P45 ATX Intel Motherboard - Intel Motherboards
and it will have more features than the ECS you listed. plus much better support IMO.
it also has a neat feature called "expressgate" which allows you to browse the internet, look at pictures, and several other things within like 5 seconds of turning your computer on. very handy of you are in a rush and need to find something really quick.
plus, its just made better.
if you ever DO decide to overclock, it is MUCH better.
more USB ports, better audio, and its a P45 board versus P43.
your decision, of course. but the asus is worth 30 bucks more IMO.
