can i OC my RIG to 4.2 ghz with this spec?

Gigabyte EP43-UD3L
4gb kit OCZ Reaper Series 1066mhz ddr2 RAM (high performance)
E7400 Core 2 Duo @ 2.8Ghz (now O/C to 3.6 stable already)
Gigabyte Superb Power supply 550w
CoolerMaster v8 CPU cooler
2x 80mm Coolermaster Chassis FAN(one exhaust one inhale)
1X 120mm Coolermaster Chassis FAN(Inhale)

Im not sure my casing air flow is good enough or the PSU is not enuf power to supply my MOBO. Btw im using a HD4770 Graphic card. Any comment?
