With a computer high end machine , it is a bit of a problem.

The expensive part of the brand machine lies in the brand premium and after-sales and other bonuses.

Therefore, it will be much cheaper to assemble a computer, and the ** of new parts is also determined by the market and performance. The compatibility of old accessories will generally be considered, but it is also your own old accessories that are considered, and if you buy second-hand accessories, the seller will also consider the after-sales service and whether the user can accept it. If I don't know how to buy a computer, I wouldn't consider adding an old part to my computer.

The assumption is that everyone has a process of going from not knowing to understanding.

The reason why the assembly master is a master is not how cheap the computer he dispenses, but how many accessories can be matched scientifically and reasonably, so that the computer is either cost-effective, or has a large upgradability in the future, or has a balanced performance without shortcomings, etc.

The specific configuration depends on the user's purpose and budget. Brand machines tend to pay more attention to stability, and the configuration and matching will go through a period of testing, which is not as flexible as the assembly machines on the market. New products that have not been tested by the market generally do not appear in the configuration of brand machines quickly.

A computer with a market price of 5,000 yuan, and a master can't configure it for 3,000 or 4,000 yuan. However, the downgrading of configuration from first-tier brands to second-tier brands is not acceptable to everyone.

It's definitely cheaper to assemble a computer than a branded computer, but all the parts are relatively not particularly cost-effective.

New parts are expensive because of a variety of reasons, such as the epidemic and insufficient production capacity.

If it is normal**, then it is normal for the assembly machine with the same configuration to be about 20% cheaper than the brand machine.

It is not recommended to buy this kind of whole machine, there are a lot of pitfalls here, this is a magic desktop.

2. The i9-11900H is a mobile processor, and the BGA is packaged on the motherboard (soldered), which cannot be replaced under normal circumstances.

3. The graphics card is even more pitiful, it seems to be RTX 3080 in the name, but in fact it is the mobile version of the RTX 3080 (the M in the M version of the e-sports actually refers to the mobile graphics card), the performance is far less than the desktop-level RTX 3080, and it is also soldered to the motherboard, which cannot be replaced at all. And this graphics card is definitely mined, and stability and longevity are a big issue.

4. With a budget of 7000, you can set up a 12th-generation i5-12600kf or 13th-generation i7-13700 machine, and the new configuration is better than what you pictured.

From the installation support station.

CPU: i3 530 box 730 or so Motherboard: Gigabyte GA-H55M-D2H 700 or so Memory:

Kingston 2G*2 360 or so HDD: Western Digital 500G 270 or so Graphics card: Sapphire HD5750 1G DDR5 900 or so Chassis:

Cooler Destroyer RC-K100-KKN1-GP 230 Left and Right Power Supply: Cooler God of War 500 RS-500-PSAP 300 Left and Right Optical Drive: Vanguard with Burning 200 Left and Rear Display:

You can choose the big brands.

For the light host, it is about 3500.

First of all, heat dissipation must be a major consideration. High allocation, inevitably the heat will also be very objective. The radiator must be selected well.

Secondly, the power supply. Power is supplied to all the hardware, and if the power supply is not forced, it is also not possible.

Finally, the chassis. The structure and material of the chassis will also have some subtle effects on the hardware, although it will not directly affect the performance, but it still needs to be paid attention to.

How to purchase: Online and offline. It is recommended to shop around, look at the average price and then find a reliable after-sales business.

CPU Intel Core i3 2120 Dual Core 730

Motherboard: ASUS P8H61-M-LE or Gigabyte H61M series 430 or so. Or other first-line brands of LGA (socket type) are 1155 pins. It's mainstream.

Memory: Kingston ADATA DDR3 4G 140-145

Hard disk: Seagate Western Digital 500G 420-430 Now most of the disks below 500g are refurbished disks.

Graphics card: CPU integrated GPU. (i3CPU integrated GPU display, no problem watching movies and small to medium games.) )

Optical drive: 80-90 or so without burning. 24x tape burn around 180-200.

Power plus case: around 280. Affordable, sufficient.

Graphics card: Sapphire Dilan Hengjin HD6750 DDR5 512MB 500-550 or so. First-line brands are guaranteed.

730 + 430 + 145 + 430 + 90 + 230 + 550 = 2555 I calculate according to the highest, and it may be dozens of dollars cheaper to actually buy it. It won't exceed 2500A keyboard and mouse can be sent on request.

This configuration is perfectly fine for mainstream games. As long as it's not JS goods, it's absolutely stable.

If you feel expensive, change the graphics card to a 6570 DDR5 512MB. Around 430-450. There is no problem with mainstream games.
