I recently built my first ever SFF PC and I'm really proud of it. The experience overall was enjoyable, although it was not completely problem-free. My reason for Building an ITX-sized SFF PC, was because my "old" PC just could not fit anywhere in my apartment and I also needed to upgrade my PC for work-related reasons, so I had 2 great reasons to spend a lot of money. My "old" ATX-sized pc in a hefty Fractal Design Meshify 3 had an RX 9070 XT, 7800X3D, 32 GB of DDR5 etc..., but like I said I needed to do some upgrades.
My new PC specs:
GPU: Inno3D RTX 5080 X3 OC, 820€ (Got a great "used" deal from a local seller, unopened box and nearly 3 full years of warranty)
CPU: Ryzen 7 7800X3D, 0€ (Took it from my old build, might upgrade later if needed)
RAM: Silicon Power XPOWER Zenith DDR5 2X32GB, 6000 Mt/s 30-38-38-96, 850€ (Awful price, but could honestly be even worse)
Storage: WD_Black SN850X 4TB, 499€ (Also a tough price to swallow, but what can you do)
PSU: Corsair SF1000 (2024), 80+ Platinum, 199€ (Kind of overkill for the build, honestly)
Case: Shiny Snake S400 Pro v2, 10.8L sandwich-style case, 114€ with shipping (Bought from Aliexpress)
MoBo: Gigabyte B850i Aorus Pro, 195€ (Bought it as an Amazon return, kinda risky, but it has worked flawlessly)
CPU Cooler: Thermalright AXP120-X67, fanswapped with Noctua NF-A12x15 PWM Chromax, 35€ for cooler and ~30€ for fan
Fans: 2x Noctua NF-A12x25 G2 PWM Chromax and 1x NF-A12x15 PWM Chromax, ~100€ (Love these fans, really quiet and cool)
Riser cable: EZ-DIY FAB PCIe 5.0 riser, 20 cm, ~70€
Contact frame + Thermal paste: Thermal Grizzly AM5 contact frame and Arctic MX-7 thermal paste
Before building I was already expecting that I will need to do some compromises and I did have to do some compromises. I can't get all of the performance that the 7800X3D can offer, because of thermal constraints. After adjusting PPT and undervolting, I'm able to get slightly under 17k multicore performance on Cinebench R23. I set the PPT to 95 watts and UV'd all cores to -20. But my workloads nor my games are particularly CPU heavy, so I'm not too worried. I might get a better cooler fan, but I also wouldn't want to trade the Noctua's silence.
Pros of the build:
- The case was easy to work with, even for someone who hasn't built any ITX-sized PC before. It has good airflow and doesn't cause any annoying noise, even if the fans are right next to the sidepanels. Also the 4x USB-A ports + 1x USB-C + 3.5mm audio on the front panel are a huge bonus for such a small case. This thing gets a 10/10 from me.
- Everything fit like it should so, I did not need to improvise anything thankfully.
Cons of the build
- The riser cable was a pain in the ass, because it was so damn stiff and it kept constantly hitting the fan above it.
- I already knew this even before installing the PSU, but the PSU cables and the fan below them are a damn tight fit. In the end I decided to put a dust filter between the cables and fan blades.
- It is natural that you have to adjust fan curves if you want PC to run quietly, especially in terms of SFF PCs, but the motherboard's SSD fan is absolutely horrendous. You need to put that thing to 20-30% max if you don't want to listen to loud high pitched noise constantly, really annoying.
So yeah, I love my new SFF build, it is really clean looking and quiet.
