I've been looking for a cheap case for the i3 combo I picked up last weekend https://www.ozbargain.com.au/node/616262
For $39 (pickup @ Umart with all stores having stock now or 1-2 days), includes both a front and rear fan (which would have to be worth $20 alone) - I think its pretty hard to go wrong for a budget build!
Thanks for posting this deal.
Needed something like this and even with the postage of $13 to Melbourne it was the cheapest option as for now.
All the very best for the weekend!
