Yes, you read it right. It is an upgrade of a home computer in the name of office.
16 years of marriage, childbirth, moving, have a small world of their own, the old with a Dell V3550 laptop purchased 5 years ago is simply not pleasant to play (eng) playing (eng) to meet the entertainment needs of the office In the name of justice, you can get a desktop computer to start! However, at this stage, a lot of investment is unrealistic. (Qiangbi), considering revisiting the upgrade of the mother’s adult stock-fighting machine, thanks to Intel’s toothpaste factory, I3-2120 on the stock machine is properly used. .
"When LZ buys something, it's cheaper to buy the second-hand fish above it, or even repair it with bad things. If you have to buy it, you must be cheeky and bargain-hunting. Watching the officials pay more attention to finding their own low prices. And it's hard to replace the sense of accomplishment with a repaired thing."

Open Jingdong I feel like I've blown up
Kingston DDR3 1333 4G Desktop Memory 249 yuan Jingdong direct link Well, the rubbish has a lot of rubbish awareness, and the free fishes have gone up. Of course, they still did their homework. Before long ago they knew that the "AMD dedicated memory stick" was a miracle stuff. Fortunately, the Intel platform did not recognize it. This kind of memory, as for the second-hand to identify whether it is fake, I tell you responsibly, climbed up a number of net text did not find a very reliable identification method, can only fight the character who let you have no money? , money can not be directly on the X East, not directly for the platform is right
At the time, the cheapest package that was found at the time, if there was more time, the price could be estimated to be low
After arrival, I found that the memory sticks that I already had were not the same as the production date, but other measles were the same. After the tests like memtest, there was no problem with the actual use.
Video card: to play the game is not enough nuclear display properly, the price is less than 1,000 yuan, compared to X East, X treasure has free fish low price and reference graphics ladder diagram, found that second-hand graphics does not fly, first of all, low prices Is likely to be pit, low-end video card tester graphics card information, and graphics card prices are relatively stable, comprehensive consideration in the selection of X East to buy GTX1050 graphics card
Innovision GTX1050 Black Gold Extreme Edition 1354~1455/7000MHz 2GB/128Bit GDDR5 PCI-E graphics card 899 Yuan Ying GTX1050 Black Gold Extreme Edition graphics card frequency 1354~1455MHz, CUDA core 640, GDDR5 memory frequency equivalent to 7000MHz, memory specification is 2GB/ 128Bit, TDP only 75W using PCI-E power enough. Heat dissipation is two 8cm fans, DP + HDMI + DVI interface. Jingdong direct link to encyclopedia Can often have special 799, when I buy is 849 sun single back to 50 Jingdong E card, coupon + Jingdou deduct 30, it counts only paid 769 Ocean, meet, but need to pay attention to this video card is no heat pipe Fortunately, TDP only 75W, and do not have independent power supply, old warm machine
It seems that the seal has been detached
Chassis: Someone brought a pillow to sleep, one day and a friend brought up an electronic control box that wanted to make a chassis DIY engraving machine, put a stepper motor driver, an offline controller, and a frequency converter, and the partner sent it the next day. The two host computers of Lenovo that had removed the hard disk and opened it, used a handful of rhythms to get a look at the weight of the host, but the design was really good. All kinds of screw-free, unfortunately can not go back line, so the LZ Soul line, please enjoy Tucao
Side cover quick release button
PCI device mounting plate can be quickly disassembled
The front panel is also a screw-free quick-release structure
Removed optical drive position, floppy drive position baffle
Due to the difference in the definition of the wiring of the Lenovo machine, it is necessary to change the line by itself. Fortunately, once successful, if you need to use it, please inquire the manual of your own motherboard, and compare the line search definition of the corresponding model (Lenovo open the chassis to change the line) to change the line.

Installation of hard disk cage: LZ hard disk has four, all 2.5-inch, just when the little friend suspected of trouble when the hard drive directly remove the hard drive cage cage, and this chassis hard drive cage can only install a hard drive, buy the original hard drive cage count On the freight is not worth the look, and finally on a 4-bay 2.5-inch hard disk cage, need to Tucao is this thing is only worthy of use, the above security lock is fully furnished, lock and unlock can open.

Installation of USB3.0 interface: This chassis is very old, only provides a USB2.0 interface, and H61 motherboard only 2.0 interface is provided, can only consider the adapter card, such as PCI-E to USB3.0 with front interface of
Music expansion PCI-E USB3.0 expansion card 2 port USB3.0+USB3.0 20PIN adapter card 68 yuan example, does not recommend this Jingdong direct link LZ Taobao search to meet the requirements of a brand called HP original disassemble card, with 19-pin front interface, NEC chip, work in all aspects far more than domestic Austrian X Division, the price is not high, 55 but did not feel to The psychological expectation is that some fishes will be resold. This kind of equipment is generally not easy to be bad. Ultimately, we choose leisure fish to start, after bargaining 40 ocean shipping

High-speed scanner: scanning more, tape feeding is a must, select the used HP 7800 double-sided sheet-fed scanner, wins in the cheap, after the seller forgot to send power, but the power interface is not 5.5/2.1 Is not 5.5/2.5, had to lead directly from the motherboard power interface, power supply with Yang 2 cut line power.

Later, it was found that the scanner scanned the paper properly, but the card was scanned and it was initially determined that the pickup roller was aging. However, this machine was very difficult to buy with a niche roller, and it was started with 350 yuan free shipping. Founder Z20D paper feeder + flatbed duplex scanner
Founder Z20D scanner A4 color high-speed double-sided automatic feeding plate 1799 yuan Jingdong direct link 
The background plate of this scanner is black and it is scanned
Asked a lot of people did not find a solution, but later stumbled upon the need to check the following options
Adjusted scan effect
Tips: but still feel bad to use, automatically identify cutting edge sometimes bleeding, from a scrapped printer above the white background board is affixed to the black background board, the world is finally quiet
Printer: Need A3 format, new expensive Kuangxiang, free fish to 800 yuan package logistics to start with an HP 5200 with a third carton and automatic duplexer, this model is still produced, and is a commercial model , It can be seen that the design is still more reliable, but unfortunately the logistics broke the third carton, you buy a second-hand printer if you do not have the original packaging must ask the seller to use plastic wrap, when broken foam, cleaning up for a long time. I found that the original ink cartridges still had 95% of the remaining, for me to print light enough for a long long time, this price even if the third box is still cost-effective, really enough thin stuffing
Tips1: If this printer encounters continuous feed paper jam, the fault phenomenon is to remove the cartridge, see there are two stopped inside, a folder inside the fixing, a drum below, the paper edge paper is very smooth, no folds Or tearing, most of the aging of the sea surface of the paper feed clutch reveals the sponge's double-sided adhesive. The clutch's electromagnet sticks to the top and cannot be reset in time, leading to continuous paper feed and jam. Dismantling can be found in the corresponding service manual.
Tips2: If it is difficult to feed paper, check the rollers and the pager for excessive wear. You can purchase domestically-made parts, which can be used inexpensively. However, you need to pay attention to only replacing the apron and use the original parts.
The print effect is great
Printer motherboard, first-class workmanship
Sansang 128MB memory module used
Damaged third tray data interface
Mouse: Asus WX-Lamborghini Mouse bought 5 years ago
If you do not pay attention to the damage, the roller is broken and repaired. After the inspection roller, the lever connecting the encoder breaks, intercepting a Hexagon bar repair.
Roller attached to the encoder on the edge of the roller broke and intercepted a hexagonal rod repair
The encoder is also broken, there is no sense of scale, can only be changed, but the encoder has a high degree of distinction, selection as shown below, measuring the height of the red box marker
My actual measurement down 5mm, but few encoders of this size, the final selection of HUANO Warner 5.5mm encoder, scale feel very comfortable, while replacing the original micro-motion for the Panasonic square brown point fretting
OLED sucker removes encoder
Square fretting is also taken down
To change the encoder and jog
Buy along the micro-motion
Several solder joints, easy to get
Handle: XBOX ONE handle

Battery cover, love XBOX logo
Router: One hundred megabits of wireless routers donated by telecommunications are enough for LZ, but if you use them for a long time, you can use them for a long time. You can only reboot and use them again. Really tired, use a 4cm fan with USB to improve cooling. Wiring must pay attention to the positive and negative poles, then the reverse will burn the fan! ! !
For warranty, fan hot melt adhesive
The printer is placed on the left side of the bay window, it is not displayed, the bookcase is installed above the 1.9 LED light, USB power supply, he changed the brightness of the two lines with the switch light adjustable
