I am considering the Antec 300 case, but I still need to find a quiet PSU that has adequate cable lengths and is also nice and cheap

My current generic 500W PSU is powering:
AMD 7750 (dual core 2.7GHz)
2x 2GB DDR2
Onboard graphics (though I might upgrade to a passive, budget card in the distant future)
Asrock K10N78FullHD-hSLI R3.0 Motherboard
upto 3 HDDs (though 99% of the time I only use 1, the other 2 are for backups)
DVDRW and a couple of case Nexus fans.
Thanks in advance for your advice.
