not haf 932 if u do not need big GPUs and heavy cooling(I say heavy ant not just good),
NZxt M59 is also good to go, IMO better -- some bucks saved will help retain his thoughts to buy core i7 which is good for him.
get corsair VX550W instead of VX450W adding 1K more
also if buying a cpu cooler then why not the noctua one which would not cost much more than N620, though N620 is also a very good cooler.
buy 6GB corsair @7K suggested above, triple channel performance will be a nice boost.
stick with HD5770 in 10K, or you may also reduce your gpu power and get HD5670 in 5-6K range. now if you think HD5770 go for VX550 and if HD5670 then VX450 will suffice, though I will suggest spend 1K and get VX550W(giving him edge in power supply), and you will never worry for making additions to your system even after 3-4 years.
