Build Log: Corsair Obsidian 800D Liquid Cooled

Check out my liquid cooled Corsair Obsidian 800D Build Log. Everything, lock, stock and barrel!
After five years of using my old – but gold – socket 775 Intel system I decide to buy me a new PC and make here a build log. Ok, you may ask, why the hell an Obsidian 800D? They are a lot newer and better cases out there! I can tell you, I’ve planned to make a build with the legendary murderbox MKII. I’ve also preordered and paid it. The murderbox MKII is the best case I’ve ever seen in the world. The only thing which I don’t like was the reverted ATX style. So I decide to buy it and revert it back to normal ATX style.

I’ve found also a very talented and genious guy named Richard ( who would revert it for me, because he has a special hand and tools for that. But after a long planning time, Richard and I came to the conclusion, that this not possible in the „quality“ which I want. So I canceled the order from the murderbox MKII. (damn Im still sad about).

I’ve searched then a while for a new case. They also was the Silverstone TJ07, the Corsair Obsidian 900D and the 800D in scope. At the end I elected the 800D, because for me its the best thing between an enormous big case (900D) and an older water cooling friendly case (TJ07). Of course for me it’s never so good like the murderbox MKII, and I will throw it so far away from me as I can, if somewhen Charles from murderbox decide to build the murderbox MKII in normal ATX style. So I will try to give my best to make the best possible build with this case whit the smal note in my head, that maybe I will change somewhen to the normal ATX murderbox MKII. Of course if Charles decide to build it in normal ATX style. The hope dies last. At following the components which I plan to install and the checklist.

A small update, have removed the lower harddisk cage to fit better the pumpt and the flow sensor.

Also I plan to make something special with the midplate. For this I will contact my cousin, he has some special cnc machines for this. I plan also to make the build so „clean“ as possible, means mask the 5.25″ cage, the motherboard tray (front and back side) as much it’s possible for me.

/Update 05.06.13:

Today I received a package from slovenia, its one part of the water cooling stuff from EKWB. It contains the EK-Supremacy, EK-FC Titan, EK-RES X3 250 and the EK-FB KIT RE4. I managed also for today the installation of the EK-FB KIT for the ASUS Rampage IV Extreme. I think at the weekend I will be able to mount the rest. Of course some images:

/ Update 13.06.13:

I’ve got a small update, this time without pictures. I’ve decided to make instead normal flexible tubing my water cooling with the not so common (but good damn looking) acrylic hard tubing. So I have ordered all the parts by For my luck I received also 8% off because of fathers day. There will also be a small update on the graphics card cooler. Instead of the „old“ EK-FC Titan, I’ve ordered from EKWB the „new“ version EK-FC Titan SE (Original CSQ) – Nickel (also with the depending backplate). This weekend I will try to sleeve some fans and so on.

/ Update 16.06.13:

Today I made some modifications on my Laing. This will help me to be able to attach them on the aquaero. So I can control the rpm of the pump and regulate the flow and the noise of it. I will call lit 3 Pin Mod.

Laing DDC 3Pin Mod 1 Laing DDC 3Pin Mod 2 Laing DDC 3Pin Mod 3

On the firs image you can see the body of the Laing and at the lower part right of the image, you see how the original cables were soldered. Starting from left. The black wire (ground) on the first pin, the blue one (speed signal) on the second and the yellow (+12V) one fourth. The assignment for the 3 Pin you can check here I hope the aquaero will be able to power all of my fans and the Laing. Otherwise I have to buy also the water block for it.

/Update 22.06.13:

Here wo go, the beast’s (water) suit. The new nVidia Titan block EK-FC Titan SE nickel and the depending backplate have arrived. I’ve installed them and they’re looking very nice and neat.

/ Update 17.07.13:

I bought also the water cooler for the aquaero. Why that? I’ve attached the Laing and 9 fans on the aquaero. This will load the aquaero very hard. To keep them cool and able to handle all that stuff was my decision to buy the additional water cooler. But the „problem“ is that the cooler is only available in raw copper. It looks a bit ugly in my oppinion. Also the fact that I have all cooler in nickel so I nickel-plate the cooler also. I looks very nice and clean now.

/Update 22.07.13:

After around two months of very intresting and lovley time, where I’ve learnd a lot and met some genious guys from the case modding scene it’s time to say „It’s finally done“! hooray!!! Before I close my project, I especially would like to say thank you to Richard (made by kier) a very! talented case modder which is sharing (not only) his knowlegde about „straight“ E22 hard tubing. Also thank you to the best colleague ever Dragan, a genious Photographer which helped me resizing and pimping the images which I shoot. Also thanks to my mate (aka. brother – from another mother) Mirza for his help during designe phase. And last but not least thank you to my CNC-cousins Avdo and Salkan. Those guys realized the dragon sign from blueprint for me. It was planned to do some more CNC modding (clean backplate and so on) but there was no more time and joy for it. With the result I’m happy. I will add only some white lightning in the case after my holidays. I hope you’ve enjoyed reading, here at least the images.
