New Motherboard and Heatsink in existing Inspiron 546 case

If you want Ivy Bridge CPU , you should choose Asrock Z77 Extreme 4 or Pro 4. They're cheap and overclock just fine (i5 3570k @ 4.4GHz)

Make sure you have decent PSU for it (For example : Antec 500W 80 Plus)
If you need a slim cooler , these ones will do the job :

Noctua is very good cooler but it's abit pricey
