Intro: Building a Tiny Server
The project consists in building a small but capable server for a home lab focused on virtualisation or similar. The end-result as a small server with full IPMI capabilities, 32G of RAM, a large SSD and an 8-core CPU running at 2.4GHz so more than enough oomph to play around. The box uses very low power and its quite quiet so doesn't need a dedicated cabinet or anything similar.
We will start with the following parts:
1x MZ-75E500B/AM Samsung 850 EVO 500GB 2.5-Inch SATA III Internal SSD amazon
4x KVR16LSE11/8 Kingston ValueRAM 8GB 1600MHz DDR3L PC3-12800 ECC CL11 1.35V SODIMM amazon
1x M350 M350 Universal Mini-ITX enclosure mini-box
1x M350-HDD M350-HDD Brackets mini-box
3x DF124010BM Top Motor 40x40x10mm Case Fans mini-box
1x P4-DC Jack P4 to DC Jack Cable mini-box
1x B002HRBB0C 4pin MOLEX Male to 15pin SATA II and 4pin MOLEX Female Power Cable amazon
1x EA10523C-120 60w (12v/5A) AC-DC Power Adapter with Power Cord mini-box
The total price comes out at around 830$ (at the time of writing the article). Sometimes the motherboard and/or memory are harder to come by on amazon. Check on newegg as well. Or your store of choice.
The power supply is a bit of an overkill in that it has more power than needed, but its hard to find reliable power supplies much smaller than that.
Step 1: Opening the Box
Let's open the box by removing the only screw in it. Couldn't be simpler!
We will also remove the factory installed bracket and the from cover. The front cover can be a bit tricky but you just need to release the two tabs and then pull down
Step 2: Installing the Cutout
We will take the back-panel cut-out that comes with the motherboard and pop open all of the optional ports except the round one marked in the photo. It should look like the third picture. Then push the faceplate from the inside of the case and push until it pops in place
Step 3: Installing the Motherboard
The motherboard will slide from the side of the box. Slide it gently and check the VGA and Serial ports to see if they are straight or bent. If they are bent, straighten them but don't use excessive force.
Step 4: Screw in the Motherboard
Make sure all the screw-wholes are aligned to the mounting bases in the chassis. Then use the supplied screws that came with the case to tighten the motherboard down. DON'T use excessive force and make sure the motherboard is well aligned and sqare with the rest of the chassis. I recommend screwing the 4 corners in a crossed pattern
- Top left
- Bottom Right
- Top Right
- Bottom Left
In the first "pass" don't tighten the screws too much. Just position the motherboard. Then do a second pass giving the screws a bit more tension - but don't exagerate!
Step 5: Connecting the Front Panel
Locate the front-panel connector. Its the one labelled JF1 and can be found in the provided quick guide of the motherboard. It's also the connector on the front right (if looking at the motherboard from the top) I recommend you take the guide and put it next to the motherboard to identify the correct pins. We need to connect the Power Button and Power led here. The colors are important!! The RED cables should be on the OUTSIDE edge of the motherboard.
We will also disconnect the front-panel USB cable since we don't have a matching one on the motherboard.
Step 6: Installing the RAM
We will now install the 4 SO-DIMMs. They are fragile so don't treat them too roughly. We will use all 4 SODIMM slots of the motherboard, but please note that they are not all in the same position. The left side is reversed from respect to the right side of the CPU.
The first thing we need to do is open all 4 levers to the outmost position. Then make sure you align the SODIMMs and watch where the notch in the connector is and that it matches the KEY in the slot itself. Then push down vertically, trying to keep both sides descending in parallel. The levers will POP back in and secure the SODIMM.
You need to repeat this on all 4 slots, but watching out for the position of the KEY/Notch of the slot as all 4 are not identical.
Step 7: Connecting the Power Cable
We will now connect the power cable from the motherboard to the case. Remove the nut from the connector but keep the split washer on it. Run the cable with the connector from the inside of the case through the hole shown and then place the nut from the outside.
Use a small pair of pliers or similar to tighten the nut but don't go crazy with the torque.
Finally run the cable to the motherboard connector (J1) and plug the end in. Make sure the Key is aligned and that it goes fully into the slot. DON'T PLUG anything into the other power socket (JPW1, the much larger one!)
Make sure the cable is not on top of the SODIMMs or anything else.
Step 8: Connecting the Front Fan
We will mount the front fan in "exhaust" mode, meaning it will push warm air out of the chassis through the front openings. The fans suck air from their rotor side (the spinning side) and push it to the motor side (the non-spinning side, where the cables pass).
We will mount the fan on the front panel and use two screws to secure it down. Put the screws in diagonal from each other. You don't really need to use 4 screws for this. Make sure not to over-tighten the screws as the plastic is very soft and can bend and block the fan from turning. Once the fan is mounted, try spinning it by hand and make sure it can spin freely.
Connect the cable to the connector called FAN2 in the motherboard and clean up the cabling with a bit of zip tie. We don't want the cables blocking the fans eventually. The connector on the motherboard is a 4-pin connector but we will only use 3 pins. The connector's KEY will show you how to properly connect it.
Step 9: Installing the SSD on the Bracket
We will now mount the SSD on the bracket. Make sure the holes are well aligned and that the "dimples" on the bracket are facing the SSD side. Use the screws to secure the disk (use all 4 screws) and then connect the power and SATA cables.
Use a zip-tie to secure the male MOLEX power connector to the disk as we don't want it dangling around in the case (it could cause a short cirtuit). Run a zip-tie BETWEEN the bracket and the SSD and tie down the cable. Make sure to tie down the MALE connector and not the FEMALE one which will be connecting to the motherboard for power.
Step 10: Install the SSD Bracket
To install the SSD bracket, connect the POWER and SATA cables to the corresponding ports in the motherboard, using SATA0 for the SATA connection. Use a zip-tie to keep the SATA cable under control or use a much shorter SATA cable. Then put the front tabs of the bracket into the nothches of the case and fold the bracket down. Screw it to the case on the rear and it should be ready.
Step 11: Install the Intake Fans in the Second Bracket
Install the fans on the second bracket as shown. Make sure the motors of the fan end on the inside of the box so that they suck air into the enclosure from the outside. Connect the fans to the two connectors FAN1 and FAN3. Tidy up the cables using zip-ties and attach the bracket onto the box.
Step 12: Closing It Up
Re-attach the front panel and place the top cover of the chassis back in place. Screw the cover back in and connect your power supply. Presto!! You're ready to go!!
Keep in mind the motherboard has IPMI so you don't need a local keyboard/screen for it! Connect to the separate nic and watch for DHCP, then open a web browser to it and login as ADMIN/ADMIN
