I was thinking of building a new pc and stumbled into the world of HTPC. This is a list of the componants I am thinking of putting into my HTPC. Graphics Card: ATI ALL-IN-WONDER 9700Pro 102-95701 ALL-IN-WONDER Radeon 9700Pro 128MB 256-bit DDR VIVO AGP 4X/8X Video Card - OEM http://www.newegg.com/Product/Produc...82E16814102365 $159 Motherboard: ASUS P4P800S-X Socket 478 Intel 848P ATX Intel Motherboard http://www.mwave.com/mwave/viewspec....ria=MB-BA20771 $65 Processor: P4 2.26 Ghz (533 Mhz FSB) $111 Case: Silverstone LC03Vhttp://www.silverstonetek.com/products-lc03v.htm $225-280 Memory:Mwave 1 GB DDR400 $86 I have a few questions regarding this setup. What will I need to do about extra cooling? I assume I will need to buy a heatsink or fan for the processor and possibly something for the graphics card as well. Will I need the optional bottom fan for the case? Also, do I need a sound card? the motherboard comes with spdif as well as mini outputs. Any thoughts on how this system will perform (mp3, tv capture, gaming) would also be appreciated.
