1: Please consider H77 for the motherboard. Even if the budget is insufficient, we should make some preparations for future RAID and SSD. Huaqing, Yingtai's H77 costs more than 600 yuan, and ASUS's B75-V costs 680 yuan. It's best to use less Gao Fushuai cards.

2: CPU, you can go to I7 3770 if you have money, and E3 1230 V2 if you have no money. The difference is that i7 integrates the display and supports some technologies, and the i7 works only slightly better at silent frequency than E3.

3. Graphics card, if you have money, you can go to Lee Tae for 2000,2600 yuan, if you have no money, you can go to HD6770, and Q2000 yuan is not available. The last HD6850 or 2G version was useless, and the static and dynamic processing were not improved. The best thing is to play games.

4: Then there is 8G memory, 1T hard disk, nothing to be picky about.

5. Chassis: 200 yuan, Cold Destroyer, 300 yuan, HAF9 12 350 yuan, En Jie Little Phantom, 500 yuan-the difference between this thing is the thickness of the plate, the design of dust-proof, radiation-proof and electromagnetic interference-proof, and shock-proof. The difference between high-end and high-end lies in silence and appearance. 100 piece of thin iron sheet is not recommended for machines of your level.

6: Power supply: Delta, Quanhan, Zhenhua, Antaike, choose one of 400 watts. Cheap is that 12V output is small, and EMC's anti-magnetic interference is similar. These brands are up to standard, just right.
