Gtx 295, 285 2g, or 2 gtx 275s?

The GTX 285 is a little overpriced if you ask me.

For SLI GTX275 vs GTX295 Tom has an entire article on the subject.

They conclude (with power consumption in perspective) that 2 SLI GTX 275 is better overall compared to 1 GTX 295. If your looking into Quad-GPU solutions in the future go with the GTX 295... but you probably won't benefit (much) from it any time soon. I say go with 2x GTX 275 in SLI.

ok, in the review it says that the practicality of the gtx 295 might outweigh the 2 gtx 275s, what do they mean by that? Oh and also im going to use a thermaltake 9 chassis for the rig, is it good for the airflow or no?

I don`t know what you mean...SLI GTX 275 seems to be faster (test proved it already) but disadvantage is that you occupy two slots at your mobo and SLI 275 is more power hungry...easy like this
GTX 285 2Gb will give you couple of fps more at high res and very high AA/AF feature but nothing significant...google it here I have found one benchmark comparing GTX 285 2gb with GTX 285 1gb

as you see no crysis improvement

and no GTX 285 can not match SLI GTX 275 or one GTX 295 but you can still SLI it when you need more and SLI GTX 285 beats SLI GTX 275 and one GTX 295

to the case..do you mean thermaltake m9?....pretty much average,nothing special. if you are going to build i7 rig with SLI/CF GPUs and probably going to overclock everything...hmmm I would go for something better (antec 1200, CM haf 932 - I have this one and it´s perfect)
