初衷
- 想组装一台可以随便折腾的主机
- 性价比要高，不要太贵
- 考虑到后面可能要部署大数据套件，性能不能太弱
硬件
| 硬件类型 | 参数 | 数量 | 价格 |
|---|---|---|---|
| 主板 | 华南金牌 x99 f8d | 1 | 894 |
| CPU | E5 2683 v4 | 2 | 1940 |
| 内存 | 2133 ddr4 16g | 4 | 1060 |
| 硬盘 | 500G ssd | 2 | 950 |
| 散热器 | 利民 as120 | 2 | 248 |
| 机箱 | - | 1 | 429 |
| 电源 | 850w | 1 | 889 |
| 显卡 | - | - | 60 |
| 合计 | - | - | 6470 |
变更
| 硬件类型 | 参数 | 数量 | 价格 |
|---|---|---|---|
| 内存 | 2133 ddr4 32g | 2 | 960 |
| 硬盘 | 1T nvme | 1 | 597 |
| 合计 | - | - | 1557 |
合计
6470 + 1557
= 8027
注意事项
- 主板两个 cpu 供电口距离过大，电源需要两条独立 cpu 供电线，如果买一拖二的 cpu 供电线电源，提前买一根 cpu 供电线
- 注意散热器支持的接口，我这里用的是兼容 2011 接口的

后记
- 两个 CPU 1940, 一年后 800~900, 血亏
