Hello. I plan to build my own computer since the DELL gx280 have given hard time to me. The i5 process would like to be my system in this time. Here is the list what I estimate on ebay (mostly) CPU: Intel Core 2 q9400 - $190 OR i5 - $200 CPU Fan: ??? M/B: Asus P5KPL-CM - $60 OR Intel DP55WB - $100 Ram: Kingston 4gb DDR2 800mhz - $60 OR DD3 -$70 Video: ATI Radeon 4850 - $124 HDD: Western Digital 500GB 32mb, 7200 rpm - $56 DVD-RW: LG DVD-RW - $31 CASE: standard ATX Tower with 500w power - $45 I have no idea about a CPU cooler. What I heard that the CPU cooler should be different ones depends on the M/B and case. What kinds of cooler can I use for my system? Also how am I able to firgue that out? Thanks.
