New PC setup, suggestions wanted

[Ferris1]

After quite a bit of forum, review, and web searching I think I finally have a parts list. To you gurus out there, please let me know if these parts should fit together and be compatible. Suggestions and alternatives greatly appreciated. I'm looking to build a fast machine for video creation, editing, and conversion as well as some gaming.

CPU: AMD Athlon 64 X2 4800+ (maybe 4400+, still with 1M cache but much cheaper, I don't have any experience with overclocking))
CPU cooler: ZALMAN CNPS7700-CU (will this fit? Anything better than Zalman?)
Motherboard: ASUS A8N-SLI Deluxe
Case: Lian Li PC-7B Plus Black Aluminum w/ Window (considering replacing with SilenX fans--is is worth it?)
PSU: Seasonic S12-430 S12 Series 430W 430 Watt ATX (will this be enough power?)
Graphics Card: MSI NX6600GT-TD128E Geforce 6600GT 128MB PCI-e
Hard Drives: 2 Western Digital SATA Raptors in a RAID 0 config (for OS and programs), Segate SATA 400GB (for data) - already have
RAM: CORSAIR XMS 2GB TWINX2048-3200PRO (2 x 1GB)
DVD drive: NEC ND-3520A - already have
OS: Windows XP Media Center Edition (has the additional networking features of XP Pro but cheaper)

THX for the look over.
