Originally a 7 x 1080ti mining rig on a Asus z270f, I sold some components and putting remaining parts (2 GPUs / motherboard / PSU) to build a new personal rig.

My love for SFF started when I built my old trusty RVZ01 ( So my goal here is to put as many powerful components as possible while keeping the small footprint. This little big box surely has come a long way, but definitely still have room for improvement (and shopping spree!).

Update (Jan 20, 2020)

  • Move a 4tb WD Green to PR4100 NAS (3 x 4TB RAID 5) and open room to fit Noctua A12x15 fan.

  • Install all 3 Corsair ML120 Pro RGB FAN and setup those controllers on the back of the motherboard.

  • Order 4 x 3rd party iCue support RGB 24-led-per-strip from ( and installed but found some issue.

  • iCue support maximum of 6 RGB strips, 10 led each so 60 LED in total. Mine is 4 x 24 RGB per strip, so only 2.5 strips (24+24+12) lit up. Time to buy another Corsair Lighting Node?


  • RGB header and M/B stop working due to the modded port bios. It is worth enable 9900k to run on this motherboard though.

  • Working in this case required you to put things in precise order. Mine is GPU>M/B>SSD>RAM>GPU>FAN>CPU Cooler

  • Lower GPU (for this inverted layout) interferes with my long PSU. I had the cut out part of plastic cover on the 14+10pin cable and loosen the GPU shroud to make it fit.

  • SLI didn't work at first but finally running under Different SLI Auto mod.

Next Step

  • Upgrade ram to Vengence LPX 32 GB 3600Mhz. CL rating is a slower but more capacity and I got a change to try to fit the Noctua NF-A15 on top of it.

  • I ordered this GPU bracket ( hoping to move one of the ML120 fan over to show it colorful glory.

  • Fit another fan using the same new GPU bracket?

Part Reviews


Buy now and/or regret later. I went with the i9 9900k for modded z270f. It didn't work immediately when I got it and I was on the verge to buy a new z390 motherboard but finally got it. Nothing to complain.

CPU Cooler

I could have go with an AIO but the radiator on the top of Raijintek Thetis would not allow an SLI configuration. So Noctua NH-D15 would put my mind at ease. Actually, I later realized I should have gone with the D15s version for better compatibility, but that extra fan is tempting.


The whole idea came when I realized the potential to mod my Asus z270f to support Coffee Lake CPU. After several attempt I managed to get it working the RGB header and RGB on the motherboard stop working along the way :(


Decided on the 16gb 3600 speed one and got the cheapest one I could find. RGB on this Patriot Viper is a nice added bonus.


Almost got a WD Black but realized how durable my old Evo 840 is, so I gave Samsung another chance. I am not quite understand the Secure Boot or CSM stuff but somehow manage to configure it as my boot drive following guides on internet.


I reused my old WD Green 4TB from previous build.

Video Card

From my 7 x 1080ti mining rig, I kept the 2 most powerful with three fans 1080tis for the SLI. The downside is the length which is proven to be a problem later on with my specific build.


Raijintek Thetis ATX is one the smallest ATX case out there that allow full size GPU, ATX PSU and large tower CPU Cooler. I knew this will be quite a toasty box, but it suits my needs so there will be many fans in this case. I wish the layout is not inverted though.

Power Supply

There were two 1200w running my mining rig: Silverstone ST1200-G Evolution and Cooler Manster v1200. I keep this one and sell the other purely for the platinum badge. This should be overkill even for the highest tier CPU and SLI config. The only complain is the length which make it so difficult to find compatible case.

Wireless Network Adapter

Working fine in open space, not so well in close cabinet.

Case Fan

These two Redux Noctua NF-P12 is running very quiet. I only hope they give enough airflow down to the CPU Cooler past the two behemoth GPUs were on the way in this build.


Got it from massdrop. First one got color banding issue so I RMA it. The second got something black stuck on the top left part of the screen. It seems to be on the upper layer so doesn't look like a bad pixel.

How hot do those 1080 Ti's run? +1

Erm, im guessing quite low when idling as it is the three fan model, but it is lacking alot of airflow as they are tightly packed together so putting it under load could be bad... not sure just guessing

Just updated the temp after running 3D Mark. idle 36-40 C load 70-86 C

Of course the bottom (in the middle of the board) run hotter.

I got worried when I saw that stock cooler in the first pic lool +1

Hahaha, 9900k doesn’t come with stock cooler. That was the cheap Celeron used for mining. I ran my rig in bottlenecking mode until I figure out the modding :)

Why do u need ultra fast memory in ur PC lol

3600 is fast but not crazy.

actually I think its OK now , some people has 4800 MHz for Intel

You are right. I was getting the 3200MHz one but the difference in price is so minimal. Anyway, I am deciding if I should switch to a 32gb Vengence LPX 3600 MHz so that I can use the included NF-A15 fan that comes with the D15 cooler.
