After reading up on some reviews on the site I decided to buy myself an Antec AMG 1080 case for my new machine. Was most impressed so that when a work colleague was looking for a new case I told him about mine and on that recommendation he got one. He had another problem, The fan blades on his CPU cooler for his P4 had got mangled while he was messing about (don't ask me how) so we also ordered some Zalman coolers which unfortunately went on back order. Next day he came in with a grin from ear to ear. His temps with the knackered fan, can't remember the exact figures,
were actually lower than before when his fan was working fully since installing into the new case.
Good ad or what for Antec? And thanks Hexus for pointing me towards them.
