LED SET UP Answered

Hi , new to instructables and have been looking at some posts and am now confused.

Im in the process of seting up a led lighting board, I am using 20 blue high power 1W led's 350mw each.

My plan is to run them from a computer power supply, but am unsure of the safest way to hook them up, parallel with a resistor for each or so on, I am basic when it comes to electronics and components, i can read a basic diagram.

Also some parts listed in high power led driver on this site are parts numbers that are not available in Australia, i know i need to regulate voltage and current at 3.5v and 350ma but don't know what parts to use, i used led calculator and was told to use a 1watt 5.6ohm resistor in parallel. Please help
