EDIT:forgot about something if you can fit it into your budget i would go with 500R just because it looks cooler(white version) has led fans and has a fan controller not to mention really good airflow for your heatsink in a push and pull Corsair 500R white
Thanks for the replies guys.
I'll get a HDD at some point, have an external one that i can use for now.
I suppose the stock cooler that comes with the i5 is not the best thing in the world, but can i run it for a couple of weeks? Should be OK
without OC i believe
