Silent Rackmount PC Build
My first proper post!
I decided about a month ago that I needed a new PC - my Core 2 Dual laptop was beginning to feel slow, despite having a ram & ssd upgrade. Also had an AMD Phenom X4 / HD 6870 Gming machine, which I never used cos I rarely play games (and that PC used to draw about 300W... Which is a lot considering our house is solar powered...)
I decided on a low profile 2U rackmount case I will be building myself, to complement my other studio gear. Will need to be as quiet as possible, so it doesn't interfere with recording in the same room, and also as energy efficient as possible. I have currently built it open on the bench, to check everything is working OK
Main uses (other than general browsing etc)
- Photo Editing using Photoshop & Lightroom
- Video Editing using Premier Pro
- Music Recording / production / Mastering (Cubase, Logic etc)
- CAD Drawing (Mostly electronic, however I do do mechanical stuff)
- Light gaming
So far I have:
- Asus P8H77-M Pro motherboard
- Intel Core i3 3225 Processor
- 2x4GB Corsair XMS3 1600MHz RAM (from Gaming PC)
- PicoPSU 160XT & 192W 12V Brick (V Rated)
- Sandisk Extreme 120GB SSD (System Drive, from Gaming PC)
- Western Digital Blue 1TB 2.5 HDD (Documents)
- Hitachi 320GB 2.5 HDD (VST Samples)
- 2x Sony Optiarc BD-5750H Slim Blu Ray Burner
- Unbranded USB 3.0 Card Read & Hub
- Intel 5300AGN Mini PCIe Wireless card & PCIe Adapter
- Firewire 800/400 Card with TI Chipset to connect to my firewire audio interface
Cooling consists / will consist of
- Scythe Big Shuriken 2 Rev B CPU Cooler
- 3 x Noctua NF-R8 PWM 80mm Fans
- Homemade Chipset Cooler
I am also using the HD6870 from my Gaming PC in the x4 Slot, until I can replace it with a low profile Graphics Card (I'm thinking Sapphire Low Profile HD 7750???) (It won't go in the x16 slot, as I have a larger cooler on the chipset.)
Also considering upgrading the CPU to a i7 3770 at some point.
Everything has been undervolted a little. CPU is down by 60mV, Ram down to 1.35 from 1.65. GPU is down to 1075mV still at stock speeds.
So far noise levels are impressive, Without the HD 6870 in, it is as near silent as can be (Using Speedfan to control fan speeds) The Scythe Big Shuriken 2 is a gem, idles about 550rpm, reaches 750 when stressing iGPU & CPU, and CPU never gets above 50 C.
Power Draw is also very good, 22W Idle without dGPU, 45W with dGPU, reaching to 55W without dGPU, 168W with when stress tested with Furmark & Heavyload.
I have made a new Chipset Cooler heatsink, the stock one was reaching 65C without airflow, so I used an old heatsink I had around which reduced temps to 44C with no airflow. (remember this is on the benchtop. I do have 2x 80mm Nocutas plugged in, but at idle they shut off)
I have yet to start building the case, although I am slowly ordering all the parts needed. I'll pop up a CAD drawing once I've done a rough mock-up... It will be constructed from 8mm aluminium plate for the sides & a central divider, 1.2mm plate top, bottom & back with bracing, and a 3mm 2U rack panel for the front.
Unfortunately no photos yet, but I'll get posting as I start building the case! (If not before!)

Managed to get some CAD drawings done, so I know what I'm building

Re: Silent Rackmount PC Build
Looks awesome!
I gather there's no practical way of using a full height graphics card with a riser? Doesn't look to be enough space since you need to allow room for the power supply.

Re: Silent Rackmount PC Build
Having the fans in the front puts the main source of noise in the front and does not cool the drives with the divider in place.
Perhaps modeling it after this
http://www.silentpcreview.com/article591-page1.html
would move the noise source and cool the drives better.

Re: Silent Rackmount PC Build
Nah, I'm going for the HD7750 low profile. Plenty enough for my needs, although I be replacing the heatsink with something considerably larger. Slot 2 has a wifi card in it, which is very short, so will use the remaining space behind that slot for a monster heatsink I've got.flemeister wrote:I gather there's no practical way of using a full height graphics card with a riser?

Plenty of room for a PicoPSU!
I wish I could, however putting fans in the sides doesn't work with a rackmount, as the side panels of the rack are in the way!Pigpen wrote:Having the fans in the front puts the main source of noise in the front and does not cool the drives with the divider in place.

I've currently got a couple of noctua 80mm PWM fans, I can't hear them at minimum speed (not that they even run in normal use, they just spin up when it gets too hot!)
Not too fussed about the hard drives either, a) they'll be powered down most of the time, b) they're laptop drives, so will if they survive encased in plastic in a lappy, shouldn't be a problem here with breathing room and c), I've put a couple of cutouts in that divider to give a bit of airflow.
Right, I'm off to cut some metal!
Re: Silent Rackmount PC Build
Hello
Very nice project, i like rack mounted pcs myself One question - do You really need two optical drives and a floppy drive? do You use them or is it just a case of option-proofing because You make Your own case?
Best regards from Poland

Re: Silent Rackmount PC Build
Yeah, I got two blu ray burners (Useful for doing disc to disc copies, I do a lot of DVDs for my dad) got em for £40 each, so absolute bargain!Horgrim wrote:One question - do You really need two optical drives and a floppy drive? do You use them or is it just a case of option-proofing because You make Your own case?
Floppy drive is actually a memory card reader, but I couldn't find any cad models of 3.5 card readers online, so I used a floppy drive as the mounting is the same! Card reader in question has USB3.0, esata & headphone ports as well, so saves me adding extra holes on the front.
Re: Silent Rackmount PC Build
Thanks for the reply.
I'm looking forward to the end result, any other rack equipment like UPS or switch etc?
Additionally, if You will have a very good quality of the cuts and all the pieces will fit each other quite nice, the placing of the fans will be irrelevant. The biggest pain is that Scythe does not produce 80mm or 92mm gentle typhoons. They are great for high air pressure.
Hest regards from Poland

Re: Silent Rackmount PC Build
Yeah, got quite a bit of rack stuff. Power amp, Firewire Audio Interface, preamp, couple of patchbays, and I'm planning on getting more!
Everything is being done by hand, so not the best quality, but should still be good enough

Re: Silent Rackmount PC Build
Today's progress
Started off with these
And got this far today

Re: Silent Rackmount PC Build
Very nice!
Is it aluminium? Kinda looks like it. Very nice cuts
some time ago i also tried to build a rack case myself but i couldn't do the backplate - all the pci cards and their mounts... also, measure everything a few times, i was using the parts manufacturers dimensions and they were off by a few mm from the real thing
Great job so far! Keep it up!

Re: Silent Rackmount PC Build
Very cool, keep the photos coming!
You could always install another exhaust fan behind your hard-drives.

Thanks! Yes, it is ali, much easier to work with, my bandsaw won't cut steel lol!Horgrim wrote:Very nice!

I'm attempting that job today, I've got a full size back panel pulled from an old ATX case I used to create the CAD model, so hopefully will be OK. I just expect to spend hours chain drilling all the cutouts...
I certainly will, I'll have more photos every day I work on it!Cistron wrote:Very cool, keep the photos coming!

I've kept that option in mind, however with any luck, it shouldn't be needed. hard drives will probably be powered down 90% of the time!

Re: Silent Rackmount PC Build
You'll probably be right too, as the mesh behind the hard drives looks to be a large and easy way for air to exit the back of the chassis. You'll likely get a good amount of air passing from the main chamber over to that side.james wrote:I've kept that option in mind, however with any luck, it shouldn't be needed. hard drives will probably be powered down 90% of the time!
Another related thought, if you're not using all the PCI expansion slots, maybe you could make some ventilated PCI brackets.
Or just buy some I guess: http://www.btostech.com/store/pc/Half-H ... s-p259.htm
Or don't use any at all?
Re: Silent Rackmount PC Build
Three of the slots will be used (7750 GFx card, Firewire card & wifi card), I'll probably leave the 4th slot uncovered!. Depends If I can be bothered to drill out one of the blanks...flemeister wrote:

I'm also going to put some holes above the slot area. The device above it in the rack is quite short depth wise, so the back 120mm has nothing above
Re: Silent Rackmount PC Build
Yesterday's Progress. Backplate done, front panel started
Found an easier way to cut the holes! Drill a few holes to make a slot big enough for a saw blade, then cut the rest with a saw!

Re: Silent Rackmount PC Build
Done a bit more over the weekend. Front panel is finished (other than mounting of buttons & LEDs etc)
Also mounted the components inside (some temporarily!), to check fit. It'll probably be a while before I can any more done (Too many other things happening) so I shall add a few photos as it currently is for you to enjoy
Front View
Rear View (PCI brackets need cutting down & rear panel needs to be inset by another couple of mm)
Dual SSDs
For those who are interested, my homemade chipset heatsink
And some homemade PicoPSU Cables (These are temporary ones, I'll be making a new set for the final build, all custom lengths, connectors etc

Re: Silent Rackmount PC Build
Managed to make some more progress
Front View
DVD Drives and card reader - I need to make a slight tweak to get the drives 100% straight
And from the back
Made a new heatsink for the low profile HD 7750 - stock cooler was rather noisy!
Also made another chipset heatink, as the old one wouldn't clear the new heatsink on the graphics card...
Sata Cable routing - I managed to get hold of some ultra slim cables, makes the job a lot easier!
New cable loom made for the power to everything
Overall view of the main compartment
Graphics card in
Modified sata connectors for the optical drives. Slim sata cables, with the power part made from a slim adapter cable with the data half cut off!
Hard drive suspension using elastic and cable lugs
Cabling by the SSD drives, power input etc. The small circuit board is a switch to allow my monitor, keyboard etc to turn on when the PC is turned on (one brick powers everything!)
And put in my rack!
Still to do:
- make the top cover
- make the front panel LEDs/Switches (you can see the temporary solution hanging out the front panel!)
- replace the car reader with one that has esata and audio as well as the USB3.0 ports. Already found the one I'm after, just trying to get hold of it haha!
- reinstall windows & get it set up how I want it
Long term plans
- Replace 320gb hdd with a 2TB 2.5 drive
- Upgrade to 16gb LP 1.35V Ram (Yes, I can quite happily max out the 8gb I've got!!!)
- upgrade to i7 3770 processor

Re: Silent Rackmount PC Build
This, Sir, is awesome! Keep it up! How are the temps and overall noise?
Best regards

Re: Silent Rackmount PC Build
Thanks
So far, even when stressing CPU & GPU, the central heating pump is louder... Hard drives make the most noise haha!
Temps are amazing as well, CPU I can't get past 45 C, GPU hits 55 C under stress, 47-48 C gaming.
I can't see any issues whatsoever with cooling an i7 in there
I'll post more detailed results once I've got the lid on, I simply placed a few magazines over the top to duct the airflow (without the lid on, gpu sits a few degrees C warmer)
