Time to finally get my new comp, any suggestions would be appreciated. (i'll probably be running vista.... )
points that may come up - I choose GTX as roughly same price as GTS here in the UK.
Nvidia chipset as I like the option of future SLI (though, its getting harder to find a GTX, so i'm worried it may be a moot point!)
RC-1000 because i think its just damn sexy (as well as pretty good airflow).
Hyper TX 2 as toms gave it a good review, and I'm assuming the q9450 is quite cool anyway compared to 6600(i DO plan to oveclock somewhat - was tempted by the Thermalright's IFX-14, but not sure it's worth it - looks a little scarily heavy!)

Feelings? Thoughts? Criticisms? Meaning of life?

I like it. These are my only thoughts:

A) I don't know UK currency v.s. US currency...so forgive my ignorance when I mention pricing things.

B) I love the Cosmos case, but I think its too much. If you haven't ever owned a full-tower case, be forwarned...they are massive and heavy. I mean, the Cosmos is almost 50lbs. Not to mention that there is no desk in the world it will fit in.

C) This is just a personal preference, I would have gone with OCZ Ballistix memory over the XMS2. I can't recall off the top of my head, but I think its a better overclocker then the XMS2 and a little bit cheaper.

Either way, I think you have yourself a really good build there...now watch ATi drop the new 4000 series cards and slap NVidia in the face...

Thanks very much - GBP to USD is about 2 to 1, so expensive, but thats just one of the joys of living her.
I'was tempted by the Xigmatek HDT-S1283, so have updated to go with it.
I've basically been delaying for ages now, and I think i'd just like to go for it. I ended up waiting for ages for the 9x00 series, and ended up dissapointed.... i can always upgrade the graphics card later if it would really benifit, or go sli (which i know people dislike, but i've seen enough good to give it the benifit of the doubt!)

Here the segate is about 15% more expensive, and for a little more thant he seagate i could go for 1TB!
On the Cosmos, yeah, i've heard alot about the size...but i can't wait!! Supersize me!

^You still might want to wait a while for the 4800, even though they will be priced high the new 4800s will drive down the prices for the 8800s and possible the 9800s.

System looks pretty solid to me. I just built one myself with 2 9600's in SLI it runs COD4 on my Samsung 24" @ 1920 x 1200 silky smooth.

I like your build.

I agree about the Samsung HD. You're better off with a Seagate 7200.11 or a WD6400AAKs or a WD7500AAKS.

Nice Build! Though, I like that you picked the 8800GTX, maybe going to the 9800GTX would be a better option. Newer chipset, G92, and likely only a small performance difference. Not sure but I think its cheaper too. That's the only thing I see here, CPU is a great choice!!

Think i'm going to edit my system and scarp SLi - i we've got the 4x series asap and then the GT200 in summer, don't think i'll get around to Sli anytime soon anyway!
--I could wait till the 4x, but what about the GT200 in a few months? i was thinking i could just buy the 8800 GTX, then wait till after summer, near the end of the year and upgrade...by the the new gen will be a little cheaper and the 8800 should keep me satisfied for a while, views?

It looks great! I still think that the Cosmos case is too much case for the parts you plan to put in it. I mean, I could definitely see you going that route if you were going SLI or Crossfire, have 4 or more hard drives, and multiple PCI hook-ups, but your going with rather a simple setup that would easily fit into a quality mid-tower such as the Antec 900, Antec P182, Coolermaster Centaurian 5, or any Lian-Li cases (the best of the best in my humble opinion).
