We'll im planning on building a new computer over Christmas break and have been doing some research the past week. This is what I have come up with, I would like feedback please . I was trying to stay around $1000 and this current build is at $1210.93, so no crazy get this $400 dollar item instead of the $200 one I have now. Case: APEVIA (ASPIRE) X-Navigator ATXA8NW-AL/500 Silver/Black Aluminum ATX Mid Tower Computer Case 500W Power Supply http://www.newegg.com/product/product.asp?item=N82E16811144089 Processor: Intel Core 2 Duo E6400 Conroe 2.13GHz 2M sharing L2 Cache LGA 775 Processor - Retail http://www.newegg.com/product/product.asp?item=N82E16819115004 MOBO: ASUS P5B Deluxe/WiFi-AP Socket T (LGA 775) Intel P965 Express ATX Intel Motherboard - Retail http://www.newegg.com/product/product.asp?item=N82E16813131028 Memory: 2x Kingston 1GB 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300) System Memory http://www.newegg.com/product/product.asp?item=N82E16820134045 Video Card: SAPPHIRE 100189L Radeon X1900GT 256MB 256-bit GDDR3 VIVO PCI Express x16 VIVO HDCP Video Card - Retail http://www.newegg.com/product/product.asp?item=N82E16814102022 Hard drive: Seagate Barracuda 7200.10 (Perpendicular Recording) ST3500630AS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - OEM Free hard drive or Notebook hard drive w/combo ends 12/11 (Comes with a free 250GB 7200 RPM 16MB Cache SATA 3.0 Drive also!!

The case already has 1x 120mm fan and 4x 80mm fans and runs cool from the reviews, so I don't think I'll need more fans since I'm not running dual video cards or 10000 RPM harddrives. The only thing I was debating on was a new power supply, I've heard mixed reviews on the 500W one that comes with my case, but I'd like to save the extra $100 dollars if I can. What is everyone's view on the artic silver 5 compound? This is my first computer I'm building from scratch, would I need to buy some of that for my processor? Also for a RAID setup, I know that usually you want matching size/speed harddrives. Because I'm getting that 250GB one for free, would it be smart to RAID the 250 and 500GB ones with same speed specifications? Would it reduce the size of both to 250GB for the raid, but could I still use the other 250GB for storage? I'm new to RAID setups. Thanks for the feedback in advance.
