The build is pretty good.
Have a look around MSY and Umart. Between them and PC Case Gear you will find the cheapest prices on most items.http://www.msy.com.au/index.jsphttp://www.umart.com.au/
Though I MUST advise against the Razer Arctosa black edition. Bought one myself, and the black lettering on black keys is horrible to work with. Currently its sitting on my shelf being unused until I can sell it off to someone else.
Currently using the Thermaltake Challenger Pro. The non-LED backlit version is ~ the same price as the Arctosa and I highly recommend swapping for that.
EDIT: Link to the keyboard. PC Case Gear was down when I first posted.http://www.pccasegear.com/index.php?main_page=product_info&cPath=113_1241&products_id=14875
