Silverstone TEK SG05 + EVGA GTX 680 + ASUS P8Z77-I DELUXE + NOCTUA NH-L12 – The ITX mini beast!

okay, so I am reducing the footprint of my computer, a LOT. If you follow, I had a 600T rig :×6950/

I am now going with an itty bitty SG05. I fought between the SG05 and the SG08 a lot, I wasn’t sure what I wanted … and the PSU only having 450W 36AMP +12V capable made me go back and forth, I felt safe going with the SG05. Since footprint was my MAIN concern. I also fought a few other boxes, but in the end, they were just too big to go ITX IMO.

Fractal Design Node size : Dimensions (mm) 250 x 374 x 210 (W x D x H)
Lian Li PC-Q08B size : Dimensions (mm) 227 x 345 x 272 (W x D x H)
Lian Li TU200 size: Dimensions(mm) 220 x 360 x 320(W x D x H)
Silverstone SG08 size: Dimensions (mm) 222 x 351 x 190 (W x D x H)
Silverstone SG05 size: Dimensions (mm) 222 x 276 x 176 (W x D x H)

So this would be my component list

Silverstone TEK SG05
Noctua NH-L12
i5 2500k
CRUCIAL Ballistix Sport 16GB (8GBx2) DDR3-1600
Crucial M4 128GB SSD
3 x Samsung 830 256GB

This was a fun build, super tiny, super compact. So far I have gamed on it for a few hours, and it’s running great. I used some Arctic Silver 5 to adhere it to the heatsink. Under full load I am seeing 46C on my i5 2500k. I have not tested much further then that though.

Here it is naked, with the motherboard, and GPU inserted. The GPU was a pain to install. I had to remove the silver bracket as well as wiggle it in. I did not bend anything, which was nice.

Here is a quick top side view :

Here’s me jerry rigging a scythe SLIM fan on top of the heatsink, because the stock one it came with was too large and hit the PSU. I have a little volt modifer that makes it super quiet, but pushes some air still. As you can see, I also put some electrical tape on the side of the heatpipes, because it is almost touching the GPU board.

I ended up removing the grill, as I could not get the screw downs to work properly, oh well. It still works, and so far no cables have touched it.

The GPU all snug 🙂 :

I will do some more extensive testing with my killawatt, and temp performance on the CPU and GPU. Otherwise, everything seems to be rock solid now. I currently have the heatsink fans in a push pull going TOWARDS the CPU, I might change it up if I get time and find some more zip ties haha. If you’d like me to test something specifically, let me know!


I flipped the PSU to push air upwards towards the vents, and it did drop about 2C under full load.

Hi there, Nice little power house you have there. I wondered if you could possibly tell me the size of the gap from the edge of the motherboard to the front of the case if there was no 120mm fan there?

The CPU cooler I have works great in this little box. A H60i would leave me just as little room, if not less from what I have read.

I would like to sleeve the cables, but I have nothing on hand to do so, as it gets cramped once you put it all in and need some room for them to move around.


Thank you for sharing this! It seems like a dream-build. I would like to ask one question from you: can you measure the weight of the full system? It would be interesting to have such a system, since it’s quite portable, but I have no idea about how much it weights! Can you measure it for me?


Why did you choose a i5 2500k over a i5 3570k 3rd generation? I believe your GPU only will run a PCI-E 2.0 instead of 3.0, other than that, nice build!

Im considering something similar

I already owned an i5 2500k, and dropping extra cash on the i5 3570k seemed pointless compared to what the perfornace differences there were (next to nil for gaming). When I built the exact rig for my brother in law, he got a i7 3770k, and when he games on mine, he sees zero difference, and our FPS are nearly identical. I have not done any thorough testing, but that is what we saw.

The motherboard actually has a : 1 x PCIe 3.0/2.0 x16 so it will run 3.0.

How much spacing (if any) is there between the front 120mm fan and the graphics card? I’ve noticed that you have the backplate installed, and i want to do the same thing but still have 2x 120mm fans in the front with a small closed loop cpu cooler radiator. Corsair H55 to be exact.

how many watts does this consume, i currently own a gtx 680 and im thinkabout build a hasweel itx build

[…] PC and thought ITX was the way to go, after building my own gaming rig on ITX, but using an SG05 ( linky to build ). We went to go look at some monitors at mirceoter, and ended up coming up with a sweet touch […]

What are the measurements of the 680GTX? The card I used was MAX without having to cut it. And no, no full size PSU. The biggest you can get is a silvertek 650 watt, which is a superb PSU itself.
