Hi I've put together what I think I want/need below. I would be really grateful if you would advice me whether or not it looks balanced and whether I'm getting the best bang for my buck (Pound Sterling actually )
I really need advice also on cooling. I haven't much idea so feel free to say if you think it will burn down the house.
Please be really honest, I won't burst into tears. Unless you tell me to get an i7 and then they will be tears of frustration.
Asus P5Q-E Motherboard =£124.99
Intel Core 2 Quad Q9550 =£281.80
Geil 8Gb PC2-6400 Quad Channel RAM Kit =£77.19
Zalmon CNPS7500-ALCU LED Cooler (CPU Cooler) =£27.42
Zotac Geforce 260² Graphics Card =£222.01
OCZ GameXStream 850W PSU =£95.22
Maxtor DiamondMax2 1 Terabyte HDD (X2) =£149.98
Sony DVD Rewriter (X2) =£33.83
CoolerMaster Centurian 532 Case =£41.11
Asus WL-138gE Broad Range Wireless PCI Adapter =£29.51
The front fan is about 60% obstructed by the hard drive cage, and is the only fan included in the case.
There are two holes in the side panel, neither of which have fans. One has an air funnel that would need to be removed in order to mount any sort of decent CPU cooler. These holes would only disrupt the flow of air through the case. You could possibly cover one with tape and mount a fan on the other.
The columns are sort of cool.
Gtx 260s are adequately cooled I think. You would not need a fan.
You would only need fans on your RAM if you had overclocked the RAM a great deal, and even then it's mostly a gimmick. Without a link to your specific RAM kit I don't know how good it is actually.
Since Vendetta = Xigmatek S1283, and Xigmatek S1283 is the second best CPU cooler made, you should choose the Vendetta. The Zalman you list was one of the top ten coolers a few years ago, but it's outdated.
I think you should get the Antec 300 + fans, or if you can afford it an Antec 900 (comes with all fans). If you prefer Cooler Master, the 690 is an excellent CM case.
