Well if your in victoria that may be the case
If your in Sydney then yea talk to Pepi first - otherwise I go
itestate.com.au
or
msy.com.au
Don't use MSY unless you want ZERO service but the cheapest price. They never pick up phones and even the warrenty replacement process is a nightmare! But they have the cheapest parts you can find.
Also sometimes its not a good idea buying from a local PC shop unless you know their reputation is good. I once bought $4000 worth of parts from a local PC store.. 3 months later one of the parts died so I went to the store to get it replaced - only to find out the store is now a bottle shop and I have no means of getting my warrenty claimed now.
