munkey, the dodgy asian men are at the swap meets. most of em are from china. quite a few of the computer stores are owned by china man as well.
i just went up to sydney last week, i didn't realise computer parts would b cheaper there else i would've looked around. went in that paddy's market, no computer stuff there.
cheapest place i've found here is msy. their parts are cheap cheap, those guys must get em cheap from some supplier.
take a look: www.msy.com.au
i dunno how dodgy they are though, went there and the store is pretty small and stuff. i tried to bargain em and it didn't work and they didn't have my motherboard in stock so i left.
