Count the dreams ！
However, the student dog is very poor , What do I do , We can only pick up the garbage as much as possible ~771 The poor performance ,2011 It's a bit of a budget explosion ,1366 Just right .
8 Disk alignment system , With a 650W still 700W The power supply , a main board ,RAID card , Fan , Two hard drive cages , And the overweight chassis . The place of delivery is Beijing , The author Tianjin , What is the freight 30 element .350 Quasi system +20 A hard drive cage +30 The freight =400 element .
Let's take a look , This kind of quasi system comes from IDC From the rack of a large company , This RH2285 It's standard 2U Rack servers , It's a big flat one . When the express arrived , Oh no , When the logistics arrives （ Pay attention to the mode of transportation ）, I watched debango drive his van and leave behind the exhaust , In the same place in meditation . I'm a weak chicken , I can't carry this stuff upstairs for a year . I remember vaguely as if 20KG？ But I called two freshmen to help me carry it （ Honey makes people ）, After a toss, I left it in my cubicle .
（ weight && Full picture ）
Okay , Quasi system in hand , It's time to purchase all the major items one by one . First, memory .ECC REG My vest is really cheap ,4G as long as 23 Yuan one , This server has enough 12 Memory slots . Buy him one first 32G~（4G*8）
And then there was CPU！ Why think about it later CPU Well , Because it's very tangled . At that time, due to financial problems , I took two E5620, I recommend you to visit friends X5570, The main frequency is higher , But is 45nm In process , Opinions differ . If you have a better budget, you can go to the sixth nuclear power plant E5645.
I used this E5620, Two pieces for shipping 90.2.4G Main frequency ,4C8T,12M Three moderations .
（CPU&& Memory group photo ）
（ well ！ Draw lots No , Pick the particles ！）
Hard disk , I choose two 146G 15500 turn SAS Two hard disks , Including freight cost 142 element . Double disk raid0 Arrays can have good speed .
（ Fighter quality ）
Although it is 2U The case , But the layout makes it impossible for us to use full height graphics cards . Be careful , One of the most disgusting things about this server is , Most of the
N card No can bright
It's very embarrassing ,GT710 All the excellent flash cards can't be used . If you want to use this server to play games , There are two options .A It's a knife HD7750 such ,B It's an external graphics card . Well, I'll choose the graphics card ：HD6790
（ The last time I got on the computer ）
Okay , It's on anyway . To realize the above image, we need to invite three things on the stage . One is PCIE Extension cord .
The second is PCIE The carrier of the extension line ：Riser card .Riser The card comes with the server , You can put a 16x Turn into a 8x And a 4x. apparently , The expanded graphics card does not have very strong performance ,PCIE The bandwidth itself is enough , Use Riser Card can guarantee better expansibility . But you know ,4x Slot insert 16x Words , The length is not enough , The right side won't fit in , So we need to saw the slot . It's a saw , In fact, it is recommended to refit it by heating . Because the material of the server is good ,PCI The trough is a good quality bakelite , All afternoon with a small saw blade . So I use a knife blade and an alcohol lamp , Heat the blade while holding PCI The other side of the trough is hot .
（ The last picture before disfigurement ）
Take a look at the motherboard before installation , And then it's going to be U On the strip, on the radiator, on the deflector ！
（ Lots of memory slots ）
（ Without the memory and the deflector ）
then , The third thing —— Magic reform 250W Power Supply . This is for external connection SATA The device and external graphics card are powered separately .
（ The initial renderings ）
We know ,ATX If the power supply is plugged in alone, it will not be powered on . How to keep it on all the time ？ see ATX Define knowable , Short circuit Pin14 and GND You can reduce Pin14 The potential of , To keep it open . And then connect it with DuPont wire , It can be fixed with hot melt adhesive , Very simple things . Then he made a few holes in an electric cooker box , hold SATA Power supply 、6pin Power supply and power port 、 The fan opening is exposed , Play an insulating role .
（ It's not useless ）
This motherboard doesn't have a sound card , and USB Very little , So we need USB HUB and USB Sound card .（7 I just need to 15 block ）
Now all the hardware problems have been solved , Into the RAID card , Put two plates RAID0, format , Loading system , to be finished ！
Then look at the performance .
Let's look at chess first .
Ah .. Not me yet 4.5G Of 2600K high , But it's better than the second wife E3-1270V1 High , Although the frame is so different . in X5570 It will be better .
Then there's Xiaochao to 900Mhz The graphics card HD6790, You can see the sum GTX650/HD7750 Be roughly the same , It took 150. Now, of course HD7750 More cost effective .
The speed of the external hard disk
dual 1366 Chipsets must be SATA2 了 . Seagate 3 Discs 2T My trash tray , When the warehouse . After a series of optimizations on the array card , Originally 130/130 This is the result of our race ！
Configuration of Auntie detection . There was no Internet connection , It's a random shot .
The last frame ends ！
