Background introduction: The emergence of the MINI-ITX PC architecture left our mainframe computer in a dark corner, entered the living room, and moved to the desktop. As an engineering geek, I also wanted to try and build an ITX console myself. Opportunity came, and a few days ago, Madame’s computer suddenly announced a strike. The inspection confirmed that the system's hard disk had been hung up and needed to redo the system. The lady said that the computer's working status has not been very good, the hardware compatibility problem has led to frequent blue screens, plus it has been disrepaired, simply assembling a new machine this time, for the installation requirements are the following: 1, the performance probably maintain the mainstream level, discrete graphics to ensure that she does not waste a few STEAM games; 2. The body size is as small as possible, easy to handle; (according to our recent life plan, the host may need to fly); 3, the price is not too expensive, the old machine hardware waste as much as possible, the alien ALPHA that finished product will not be considered. It seems that I do not need to propose this time but also to assemble an ITX cannon. Hardware selection: 1 The choice of chassis The ITX chassis on the market can be quite diverse and varied, but after considering the size, price, and configuration requirements, I don't think there are many choices. Yinxin ML09 According to the body type, the best choice in the mass production chassis is Silver Shine ML09, 350X99X250, 7L. This is a slender body chassis that is easy to place and can be easily put into the boarding luggage. The price of Yinxin ML09 is not high, but it is an SFX power supply chassis, which means that I must add an additional power supply (the old machine's power supply in 2015 will be in good working condition, but unfortunately it will be discarded), and the investment will increase a lot; ML09 supports discrete graphics cards, but due to space limitations, only knife cards (half-height cards) can be selected. There are not many options. Cards on the midrange or above do not have a card-on-a-card version, and the upgrade capability is limited. Finally, the same gods who use the same chassis are used. Tell me, ML09's chassis structure is relatively difficult for the graphics card cooling, heat inside the box is easy to gather, not suitable for the assembly of high-performance host, so I did not choose this one. Yinxin SG13 According to the price optimization, I think the same SG13 from Yinxin more meet my needs, 222X181X285, 11L is still very MINI size, support ATX power supply and 3.5-inch hard drive, the price is only in the early 200, you can use the budget more to enhance Performance; However, after doing some homework, I discovered that this chassis structure also has the problem of heat concentration, and the need to install a water-cooled system to separate the heat source is an additional investment. On the other hand, the internal space of the SG13 is limited. Although supporting ATX power supply, but I am afraid it is difficult to accommodate the traditional power cable, the final will probably need to replace the SFX power supply or module power supply, the investment will rise again; Finally, users of the SG13 generally said that the chassis workmanship, the combination of poor, The plate is too weak and deformable, so I gave up this lovely little box. Lian Li Q34 Lian Li Q33 is a famous classic product in the ITX installed circle, Q34 is a small change in its appearance; Q34's body is very burly, 229X250X330, the volume reached 18L, in the ITX chassis is a real big guy, thanks to the huge The volume of the Q34's interior uses a layered structure, the power supply and the motherboard is divided into two regional arrangements, to avoid several heat sources, a huge upper space can be installed on the traditional tower radiator, to further ensure the cooling capacity of the chassis; workmanship, Lian Li's reputation has always been very good, with solid materials and good workmanship; in terms of price, Q34 is small but expensive, but plenty of space allows me to comfortably arrange non-module ATX power supply, saving a sum of money; fish and bear's paw can not have both , so I decided to assemble the ITX console for the first time, or a little more stable, choose a simple Q34 2 System Architecture Selection My wife initially gave me a budget of 3,000, on the grounds that "anyway, all of them are to exceed budgets, which are set to be lower"; under this budgetary control, my first consideration is the INTEL four-generation HASWELL architecture, which can be used with B85 motherboards. The machine's 8G DDR3 memory makes the best use of the 450W power supply can continue to play the remaining heat, if you use four generations of I5 4590, with GTX1050TI graphics card, the total budget can be controlled in the early 3000s, even if the graphics card use GTX1060, also in the 3500 grade, you can The cost is very high, the only problem is that the motherboard can only be used to scouring... After doing a good job reporting to Mrs., the result of Mrs. Lao said that the structure is too old and not very good. She hopes that the computer will retain certain upgrade space. After three years of the new three years, the old three years will be used to make up for three years of fighting to ten years. Do it again to 4000. Using DDR4 architecture, the current conventional choice is the i5 7500 CPU with the B250/150 motherboard. Although the i3 on the 8th generation is awesome, the price of the corresponding motherboard is too high, so it is not considered. In accordance with the principle of being able to save provinces and provinces, the main board has chosen the low-end B150 and the CPU has seven generations of i5. 3 Other Hardware Options RAM I have to say that watching the price of memory soar at a speed that is visible to the naked eye really makes me feel pain in my body. However, the memory of 8G cannot always be streamlined, and you can only choose the lowest possible price. SSD If it is my own machine, I will choose to add SSD later, but this machine is for the wife, so in order for her to intuitively feel the progress of the hardware, an SSD is essential. Video card The choice of video card caused me to tangled for a while, because after the other accessories were decided, the graphics card within the budget was only GTX1050 type (A card is slightly deeper so did not consider); but the video card this thing, you ask 100 people, will There are 1000 people telling you that the GTX1060 is more cost-effective, so forget it, or 1060, the machine is ready to fight ten years, the starting point is still a little bit high. The final configuration determines: Over a lot of right, in fact, out of the old memory can also return blood 400 + (have been shot), the rest I secretly to the mat, with his wife said the chassis 100 to buy it ... Purchase and assembly: Chassis For Q34's volume, although I was mentally prepared, but physical still made me quite hit, 18L's volume is about half the size of an ordinary desktop chassis, shaped like a large bookshelf speakers, the lack of a small and exquisite feeling, put On the desktop, the pressure is still very big. However, the shape of Q34 chubby pier makes it not too long on each side, it is not difficult to store it in the trunk, in line with my needs Lianli's workmanship is indeed outstanding. Q34 is the best chassis I've ever used (I haven't really used a higher-end chassis). The chassis plate is thick, the combination is accurate, and the black brushed surface is quite textured. The only fly in the ointment is LOGO is a little earthy... The screw fixing the case also comes with a rubber gasket, the details are very hard Chassis origin is Taiwan The side panels of the chassis are fixed by snaps, which can be loaded and unloaded with bare hands. It is very convenient and accurate. The old caps that have not been installed for several years indicate that this design is really alike. Chassis side plate Next is the most characteristic opening and closing mechanism of the Q33/Q34 chassis. The chassis is opened by a hinge, and all internal spaces can be opened without tools, reducing the difficulty of installation. It is very suitable for ITX newcomers like me. Instructions and accessories, description is still in place, the use of each part has a description Chassis purchased from the down payment home, price 549, link to put Tmall. Motherboard Motherboard selects ASRock's B150, without him, price sorting options, benefits... The first time I saw the ITX motherboard, it was really MINI CPU Boxed I5 7500 price is still very high, intertwined, valued friends suggested that I choose Taobao's flicks, once the CPU is difficult and bad, and second, there is no way to fake, reliability does not need to worry. I think it is reasonable, so I decided to choose a piece of film, the price of 1089, sent a paper box, no, plastic bags, a roll of mail ... probably ... ... no problem. Remove the clips to install the CPU, tightly fit (nonsense) heat sink Considering that the chassis is a big guy, the radiator naturally chooses a low-cost, high-efficiency tower radiator. Value friends recommend Kyushu Fengshen's Xuan Bing 400. This is just a Jingdong PLUS special price, apply for a trial member, 88 start. Of course, silicone grease comes with its own, reflecting my careful planning Index Finger Grease Install the radiator Compared to the compact ITX motherboard, the tower radiator is very large Memory and hard disk Memory is A-DATA's 8G general rule, hesitated for a few days the price has climbed about 30 or so, finally 599 start, two words, meat hurts...... SSD also comes from A-DATA, the smallest series with the lowest capacity... But the dead camel is bigger than the lean one. The low-end solid is also solid. Compared to 3.5-inch old HDDs many years ago, the speed increase is still huge. The mechanical hard disk uses a 3.5-inch 1Tb hard disk. Since the hard disk is a thick disk, the hard disk drive included with the chassis cannot be installed with another 3.5-inch hard disk. Therefore, the other location is used by me to fix the SSD, as opposed to the front panel. This is more conducive to heat dissipation The old hard drive, which stores the substrate and animation of this lady baby... Hard disk tray, thick material After installation, screws can be fixed on the chassis by hand The video card selected is the MSI GTX1060 OC 3G short card, which has only a limited budget of 1060. The Q34 graphics card is limited in the horizontal length. Only the short card can be selected and the short card is used for the first time. power supply The power supply also comes from the old machine, rated at 450W ATX power supply, before the arrival of the chassis I was most worried about whether the power supply size is compatible, and finally installed smoothly, finally relieved Chassis fan The fan wanted to solve the 20 points simply, and he accidentally read a local installed website, and then became this... The tragedy is that the position of the chassis to install the fan hole is too large, you need attachments to install, I had to find the gasket first installed temporarily, waiting for the arrival of special washers The accessories are all ready to be installed inside the chassis. It's still neat and tidy. If there are no power cords, then... After soul line, the installation is completed This time the installation is still very smooth, and everything is normal after the installation. Although the first time you use the USB flash drive system is a little unfamiliar, all the problems have been solved in a few hours. Place Although the Q34 is very large, I still put it on the shelf next to the desk. The two machines are stacked, which is still relatively space-saving. In contrast, the alien ALPHA is really small... It has to be said that assembling an ITX host is a very interesting experience. Once you install it, you will think about it and reload it. It will be even more difficult to install a smaller one. As the city of residence changes, the desktop in my home has been rested for a long time. It will be converted into ITX small host to the side, the next time, try to convert into A4 host in one place.
