Recently, the Sinoc ore plate seems to have collapsed. The price of a stack of Sinoc mining machines sold on salted fish is about 300 yuan, and most of them are shipped from Zhengzhou, Henan Province. I'm free. I bought a 268 Softcoin without a hard disk. Take it apart and have a look.
Express delivery
Debang, a salty fish seller, spent 2 days from Henan to Beijing. I didn't get up when I received the package, so I quickly got dressed and washed and went downstairs to pick up the package.
The seller stuffed a lot of bubble paper into the box, which was very large.
Appearance and rear interface
The case of the Sinoc slag minicomputer is similar to an ordinary ITX case. I use the Xbox handle to compare it, but it is not much bigger.
The rear interface is very poor. There are only basic USB, video and Internet ports, and no audio interface (the castrated version of the Qirainbow motherboard is the same model, and the full version has an audio interface).
I used a box ruler to roughly measure the next size for reference.
Disassembly: hardware configuration and internal structure
a main board
The motherboard is seven rainbow C. Q1900M all solid state version V20A , relative to V20 Full blood version, V20A The most obvious is the castration of the rear audio interface, and the empty pads are clearly visible.

- The motherboard has two native SATA2 interfaces, which seems insufficient for NAS.
- Three PCI-E slots are provided, which can be used to connect expansion cards. It is also good to transfer out two SATA slots.
The PCI-E will be described in detail below.
Memory
The motherboard has two standard DDR3 slots, and the machine is equipped with a 4GiB 1333Mhz ordinary bar by default.
Note that the official website of Qicaihong wrote that "DDR3 dual channel 1066/1333Mhz memory is supported".
Fan connector
The motherboard has a 4-pin CPU fan interface, which is located above the first pic-e x1. Qihonghong says it supports speed regulation.
At the same time, there is also a 3-pin fan interface in the southeast corner of the motherboard. If 3-pin wants to speed up, it can only rely on DC to speed up.
PCI-E interface
First of all, there are four PCI-E channels available in J1900, so the PCI-E x16 slot on the board cannot be x16.
Students who want to insert an expansion card in the PCI-E position should pay attention that the chassis does not have a PCI slot, and there is a hard disk rack above the PCI-E.
As can be seen from the above figure, the distance from the top of the PCI-E slot to the bottom of the hard disk rack is 5cm, which means that if you plug in all the hard disks, the height of the expansion card should be less than 5cm, and the tailgate needs to be removed.
How can I fix the expansion card without the tailgate? Hot melt adhesive, please.
Enigma front horn
Although the motherboard has castrated the back audio interface, it retains the onboard audio jack. There is a speaker module in the front of the chassis, which gets power through the large 4pin, and gets sound through the on-board audio jack.
Power Supply
Very common sfx OEM power supply, model Sinoc S326 , rated power 200W, maximum power 300W.
There is nothing to say about this power supply. The j1900 does not use a good power supply. The power supply+12V is marked with 180W (MAX), and+5V and+3.3V are marked with 80W (MAX, sharing one circuit). If there is no virtual mark, it is not unusable.
summary
Sinoc slag floor chassis is of good workmanship, and the board looks better than that of Snail Star. However, Snail has its own SATA expansion and pluggable hard disk rack, and Sinoc needs to open the chassis every time it changes the hard disk, which is inconvenient for NAS users.
Today, the price of Snail Star has risen from more than 200 yuan to 350+yuan, while the price of Sinoc is only over 300 yuan (with 60GiB SSD), which is still worth the price.
