這樣子的配備需要水冷嗎?

有以下幾點建議:
1. PSU: AOpen FSP300-60ATV
2. Mainboard換成KM400A的, 推薦Gigabyte 7VM400AMF, 規格如下:
Supports AMD Athlon™ XP 400MHz FSB processor
Enhanced system performance with DDR memory
Supports AGP 8x interface for outstanding graphics performance
Integrated 10/100Mb Ethernet controller
Integrated 6-channel AC’97 audio with S/P-DIF function
Texas Instrument IEEE 1394 FireWire interface
Integrated GIGABYTE patented DualBIOS™ technology

or MSI KM4M-L也不錯, 只是這款是 KM400 的而已, 但較便宜
