Of the two cases you have listed, I would go with the Centurion 590, just make sure you mount the PSU with the fan upwards, as there is no dustfilter for the PSU intake mesh on the case.
If you could spend $10 more I would go with the LIAN LI Lancool PC-K58 Black.
Case / PSU - Bigger and Better cooling, better quality PSU - Antec Nine Hundred + EA650 Power Supply and $10 less than your Antec Combo at $180 .... 650 watter can handle two of ATI's top of the line 58xx series cards in Xfire. 750 watts is an oddball size .... today, for the top tier single GPU cards, a 650 watter is more than enough and for twin double GPU cards in Xfire, an 850 watter will do it. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
thank you for your suggestions. i'm buying the 920 for $220 after tax from microcenter. i don't see the 930 on their website yet. i'll try to get that if it's the same price if i do see it.
the i7-930 is brand new and just comes out this sunday (in Europe, i don't know about the US). The price-point forecast is about 280$. some stores already have it for a more expansive price but the big ones don't, so you can't compare well just yet.
1) Jack hit the nail on the head with his Case/PSU recomendation. If you are planning on upgrading GPU's later make sure you get a case that will fit the bigger cards....It would really be a shame if your case ended up being a bottle neck... The 902 is a great case or you could always look at my favorite which is the HAF922. The HAF922 will fit any card you buy with out any modifications.
2) Do you need a Hard drive? You did not list one. If you do I would suggest the WD Black 2TB or the Samsung Spingpoint F# or the Seagate 7200.12 for smaller drives (500gb-1Tb range)
930 is supposed to replace 920 in near future cause as we know lynnfield beats 920 in many places and is a super power saver.
the launch price of 920 ,860 and 930 is same $284.
online sites prices vary a lot.
the only problem wth lynnfield is u would stick wth quad core, though i dont think that would be a problem for many. as long as 870's big bros keep coming on 1156.
if u go for bloomfield or 1336 ull have room for upgrade to six cores. core i7 980xe is the first one coming march 16 for $999.
and core i7 970 for $562 in Q3.
well if u can hold ur horses thn i thnk arnd march 16 the prices will see changes , u may get 920 damn cheap or 930 few more $ cheap.
just close ur eyes and wish looking up in the sky: "show me the wisest config to build "
