The computer at home finally broke down,
buying a desktop is not my style,
today I will share how to transform a server.
First, we need to have a server,
on X treasure, a decent server costs about 500-1500 each,
as a qualified junk collector,
you must reduce the price to the lowest,
not spend a penny more.
A server like this only costs over 500 yuan,
it has a power supply, a motherboard, four hard drive slots, and comes with two memory sticks
(second-hand, servers generally have a long lifespan)
it does not come with memory or CPU, but has a RAID card,
the RAID card is a disk array card that can combine multiple hard drives into one,
used for backups, mirroring, and redundancy, to prevent data loss.
The CPU is also quite cheap,
the E5-2640V3 2.6G 8-core 16-thread only costs around 400 yuan.
The performance of the E5-2640 CPU is very high,
comparable to an average I7,
according to the performance score, it scores around 120,000 points.
However, such an expensive CPU,
I won’t buy it,
because it does not fit the identity of a junk collector.
A 16G memory stick only costs 160 yuan.
What surprised me is that
this server is too noisy,
the noise is huge,
without a decibel meter, it’s hard to measure,
you can hear it through the door.
The black rectangular object above is the fan, with a total of 5 sets,
two in a group, series-connected turbo fans,
with a speed of up to 15,000 RPM,
since there is no machine room at home, I can only modify it.
Take them all apart.
If you buy,
don’t buy a 1U server,
2U is just right, U is a unit of thickness,
one U is 46mm thick, 2U is about 92mm
2U is also convenient for expansion functions.
You can use a large graphics card,
otherwise, a PCIe connector costs over 30 yuan.
Measure the size (standard 1U server)
Then I drew a picture, customized a rack, and stood the server upright to save space
This rack was exchanged for two boxes of cigarettes, made from scrap materials.
The welding master said it was a generous gift.
To reduce noise, I also removed the passive cooler, leveled it, and installed a fan.
To smooth the heat sink, I even used a machine from 1968.
The 1U server is too thin, I had to use an angle grinder to make a hole,
to facilitate ventilation and heat dissipation, now there is no other noise except the sound of the fan.
The CPU’s normal temperature is 45℃
It looks pretty good under the table, right?
The black tape on top of the rack is tape.
Also, the server does not come with a sound card,
you can buy a connector (10 yuan) HDMI to VGA cable,
the graphics card all have HDMI ports,
most HDMI ports come with audio.
Plug this into the graphics card, install the graphics card driver, and you will have sound.
This looks pretty cool, right?
The entertainment master scores around 100,000 points.
I use CPU E5-2420, this CPU is very cheap, only 15 yuan each.
Two cost only 30, about the same price as a CPU fan (fan costs 10 yuan each).
Memory can’t be less, buy four sticks for 340 yuan. A total of 32G memory.
Interestingly,
after installing a dedicated graphics card,
the integrated graphics card can also be used,
can connect three monitors.
I feel that this server can be used for 5 years
