I appreciate the discussion fellows, but perhaps I should shed some more light on this. The case itself came with 3 Antec Tri-cool fans built in. I ditched these soon after as they are speed controlled by three individual switches, one of which is just loose inside the case (so stupid) and the other two are on the back of the case! To me that is pretty daft.
I removed all three antec fans, and replaced with 4 120mm fans. From the pics you might be able to see one at the top, one at the back, one at the front, and one right at the bottom in the middle (between the hdds and the psu). Three of these fans are Hiper case fans (http://www.ebuyer.com/product/105137
) and one of them (the back fan) is a Xilence Red Wing fan (http://www.ebuyer.com/product/138586
) which seems to have excellent reviews, 5 stars all round apparently.
Listen to what I plan on doing, and let me know your thoughts. I'm going to buy a HD 6950 vid card, as I've got the eyefinity bug and my rampant consumerism tells me I must have it! I will buy two more cheap 23 inch monitors. In addition I'll get a coolermaster cpu cooler, and I'll do some research on a vga cooler for the HD 6950 (suggestions welcome as always). I'll be overclocking my Sandy Bridge, and I fear that all these additions will be too taxing on my trusty Antec Neo HE 500w psu, so I might have to get another one.
After all of this, I will sell a kidney. Honestly, upgrading PC's is akin to having a drug habit.
