Hi, thanks so much for all of your replies.
As for the SSD, I found a better deal with a SAMSUNG 128GB SSD, so I'm going with that.
The PSU, not expecting such fast feedback for the forum, I went ahead and bought a 700W PSU by Scythe (Japanese make) as it was 80+ Bronze certified, and had a 4.5 star review. Corsair PSU's, due to my location, are relatively expensive now (with the pound getting stronger), and was a bit out of my reach.
If the PSU I bought turned out to be BS, I'll consider installing a Corsair PSU!
For the CPU cooler-I'm not immediately building the PC, so I'll look for good deals on the internet.
Anyway, thanks a lot for your advice.
Is the Zalman Z9 case any good for airflow?
