My rig good enough?

I had no intention of buying anything today, and ended up puttin an order down for a $2000 dollar rig... go me and saving.

Anyways what i ordered was

Antec 900 gaming case
Thermaltake 850 tough power psu
xfx nforce 680i lt sli mbrd
intel core 2 quad q6600 2.4ghz 8m gostep cpu
corsair twin2x-2048-pc6400c4 2gb 800mhz ram
western digital 350gb hd
xfx 8800gt 512mb videocard

I have 2 questions..

1)should i change the case for an antec performance 180b? id like to see the insides,
however my antec superlanboy atm gives me trouble at night due to the blue led, i cant sleep with it on..

2) will this be good enough to run dx10 games (WiC and Crysis) on high level settings?

cheers in advance

EDIT: gamespot no spaces

Good enough? Sir, that takes most systems, shoots them and sleeps with their sisters.

[spoiler] In otherwords, yes on the second. The first question is particular to what you want, although not much has better cooling than the Antec 900 [/spoiler]

im using stock coolers (budget at its limits), the performance tower be ok? wont like fry my cards or anything?metalisticpain
