singh246 :
I haven't made this PC yet but am hoping to. It will be my first build so please give me some advice on how to improve. And tell me weather the components are all compatible with each other.
Case – Antec 900
PSU – Antec NeoPower 650
Motherboard – Asus P5N-D nForce 750i Sli
CPU – Intel Core 2 Quad Q9450
Graphics card – EN9800GTX TOP/HTDP/512M
RAM – OCZ PC2-8500 Reaper HPC 4Gb
Hard Drive – Western Digital VelociRaptor 300Gb
Optical Drive – Pioneer DVR-212BK
Case Good, Always have liked Antec cases, and that one is a nice one.
PSU - ......Might cut it close if you ever decide to run SLI. For a 650w I'd go with this one
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005. Should be able to easily handle that setup, and SLI. Thats also a really good deal at that price.
For 750w here is another good one from Corsair, good price too.

Motherboard - Not really a fan of Nvidia based boards, unless you're dead set on eventually running an SLI setup. I'd recommend maybe an Intel P45 based board, like this one, that is just about in the same price range.
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131296 . Not to mention, the disk performance on the Intel based board would likely blow away that of the 750i boards. You could then still use the 9800gtx, if you didn't plan on SLI, or possibly get yourself an HD4850, and be able to upgrade to an Xfire setup in the future.
CPU - no problem there, pretty good cpu for the price.
Graphics card - pretty solid performer, but you also have the alternative of one of these.

I point that particular one out because they currently have a combo deal going with the p5q pro board, which as far as I can tell is almost the same thing as the p5q-e, just has a different heatpipe layout, and on board sound is different.
Ram- that choice is good, but would be wasted on a 750i board, since that one can only use up to ddr2 800. Alternative, this one I am using myself with my setup, it costs about $12 more, but also has better latencies, and runs on less voltage.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820146785 , I've never had any issues with Mushkin.
HDD - I don't get matching a velociRaptor drive Raid setup with a board that wouldn't be able to keep up with the data throughput. A p45/x48 board maybe, but, not with a 750 or 780i board. In fact, unless you're really particular about disk performance you could very likely save a chunk of money by using a couple decent seagate 7200.11 barracuda drives. Then you could put the extra money to a better PSU or second GPU, which would do you better in gaming.
Optical Drive - Couldn't find the one you listed but I'm going to assume it's similar to this one.
http://www.newegg.com/Product/Product.aspx?Item=N82E16827129020 , not a bad drive, been thinking about picking one up as my secondary optical drive, so I can run it along side the hp dvd1040i. Don't know if I'd worry too much about lightscribe until they make it capable of doing color labels.
CPU HSF- Though the cpu you're getting will come with a stock fan I always recommend getting aftermarket.
http://www.newegg.com/Product/Product.aspx?Item=N82E16835887011 This ones a good one, just make sure they include the fan speed controller with it, otherwise its loud at full speed, I use one myself and it cools the Phenom 9850 fairly well, hangs around 29c idle, and never goes far above 40c under full load even during this time of year in Texas.
http://www.newegg.com/Product/Product.aspx?Item=N82E16835233012 This here is a really good lower cost hsf, and recommended by many on this forum.
http://www.newegg.com/Product/Product.aspx?Item=N82E16835154002 This is always a good performer and for a long time was considered king of the hill, along with the TRUE 120.
http://www.frozencpu.com/products/6..._775_AM2_754939_940_F_771_604_.html?tl=g40c14 That one right there, along with the Thermalright IFX14 are the new kings of the hill when it comes to cpu coolers. Only problem with that Noctua would be finding it in stock.
