For sub-10L builds, which airflow mod actually made the biggest difference?
One thing that makes SFF builds interesting is how much engineering goes into managing airflow in such a limited space.
Custom fan ducts, 3D-printed shrouds, modified panels, and carefully routed cables can all make a difference, but not every mod necessarily translates into better cooling.
I'm curious which airflow modifications have made the biggest measurable improvement in your builds without adding too much noise or making maintenance difficult.
If you've experimented with any of these, it'd be interesting to hear:
What case and hardware were you using?
What modification did you make?
Did you notice a meaningful difference in temperatures or noise?
Was the improvement worth the extra complexity?
Bonus points for before-and-after temperatures or pictures of your modifications. Practical ideas from real SFF builds are always interesting to learn from.

Anyone fit a PNY 5090 (or any oversized 5090) with a WVP2 in an SFF case?
Currently running a PNY RTX 5090 ARGB Epic-X in an NCASE M2 with a Corsair SF1000 and a Corsair 180° 12V-2x6 adapter. It fits, but it's tight, like 1mm or less of clearance tight and I'm looking at adding a WVP2 while keeping the classic layout. I don't think an M3 would fit it.
Has anyone actually pulled this off with a PNY 5090, or another big triple-slot 5090 (Astral, Suprim, Gaming OC, etc.), in classic config in any SFF case? I'm open to other cases if the M2/3 is a lost cause.

Arctic p9 vs noctua NF-A9?
For rear intake on the ncase m2. With the thermalright PA 120 mini. The arctic p9 is insanely loud against the rear grate, and adding a spacer didn't seem to do much. There is significant motor noise, not just air noise, and its a very irritating pitch too. Is it worth spending double the the money for the noctua, considering it moves less air?

Highly portable 6-9L SFF - Case/Bag/Monitor/GPU advice needed
Hello, first time PC/SFF builder and need some guidance on how to finish my build and what bag/monitor options I have.
This build will need to be highly portable/rugged and as lightweight as possible. It will travel with me on ferries/helicopters/across desert..etc
It will be mainly used for gaming with a KB/M & controller, but also for work and perhaps some dabbling with local LLMs down the line.
Parts already sourced (driven by deals):
\- Motherboard: ASUS ROG STRIX X870-I GAMING WIFI AMD AM5 X870 Mini ITX
\- CPU: AMD Ryzen 9 7950X3D (AM5, 4.2GHz/5.7GHz Turbo, 16-Core)
\- CPU Cooler: Thermalright AXP90-X53 Full Copper Low Profile (53mm height)
\- CPU paste: ThermalGrizzly PhaseSheet PTM 50x40mm.
\- RAM: G.SKILL Trident Z5 Neo RGB DDR5 64GB (2x32GB) 6000MT/s CL30 (Matte White)
- GPU Option 1: ASUS Dual GeForce RTX 5070 12GB GDDR7 OC Edition
249 × 126 × 50.6 mm
- GPU Option 2: ASUS GeForce RTX 5070Ti Prime OC Edition
304× 126 × 50 mm
- GPU Option 3: XFX Mercury AMD Radeon RX 9070XT OC White Gaming Edition with RGB
360 × 155 × 72 mm
\- Storage: Crucial T705 2TB PCIe Gen5 NVMe M.2 SSD (with White Heatsink)
\- Power Supply: ASUS ROG Loki 1200T SFX-L 1200W 80 Plus Titanium
\- Fans: 2 x Noctua NF-A12x25 G2 PWM 120mm
\- Case: [input needed\]
\- Monitor: [input needed\]
\- Bag: [input needed\]
GPU:
Out of the three options I have, I think the 9070XT is too big for anything SFF (my target is 6-9L). The question is 5070 DUAL or the 5070TI Prime? If I choose the prime, by how much am I raising the minimum case-volume required?
Monitor:
I initially entertained the idea of an ROG XREAL R1 VR glasses due to footprint/weight - but its not sustainable for more than a few hours of gaming or in the long run due to inability to perform productivity tasks/text clarity/eye strain.
I do have a portable OLED: UPERFECT UColor O Pure 15.6" OLED Portable Monitor 4K USB C Laptop Monitor but I feel 15.6" is a bit small. I did see a UPERFECT 23.5" that comes with its own slip-in bag - just not sure how it will fit in whatever bag I decide to get for the SFF PC.
Any suggestions for a big immersive screen that is lightweight and still portable? Perhaps something foldable?
Bag:
Claude recommended me to get Manfrotto PRO Light Backloader M backpack if I end up building in the DAN A4 H20. For the veterans here who daily carry SFF's what bags do you usually recommend for a sub 10L build, that also needs to fit the monitor, accessories and cables.
Case:
I have been looking at the below options, but not sure which one I should go for:
|Case|Volume|Weight|
|:-|:-|:-|
|ShinySnake L300|8.5 L|2.0 kg|
|ShinySnake S400 (KXRORS)|10.8 L|2.7 kg*|
|FormD T1 V2.5|9.95 L|2.8 kg|
|Lian Li / DAN A4‑H2O|11 L|2.9 kg|
|Fractal Terra|10.4 L|3.1 kg|
In addition to METALFISH T60 Mini - 9L - 2.7kg, which seems like a great option since it can come with lightweight pre-perforated acrylic side panels, just enough around the GPU/CPU fan area and I feel that that will keep the dust/sand out much more effectively than the typical full top-to-bottom mesh side panels found in other panels.
I would like a case that is rigid/lightweight/backpack friendly - something that will protect my GPU inside (maybe a FormD T1 with a GPU sag/travel kit?). I am not even sure if all of them fit my exact components. Would very much appreciate if someone has built in all of these sheds some light.
Weight:
|Part|Weight|
|:-|:-|
|Lian Li A4‑H2O case|2.90 kg|
|ROG Loki 1200T PSU|2.15 kg|
|ASUS Prime RTX 5070 Ti OC|1.17 kg|
|ROG Strix X870‑I|1.05 kg|
|Thermalright AXP90‑X53 Full + fan|\~0.60 kg (heatsink alone is 0.54 kg)|
|2 × Noctua NF‑A12x25 G2|0.39 kg|
|RAM, CPU, SSD, PSU cables, riser, screws|\~0.5 kg (estimate)|
|Total|≈ 8.8 kg|
I would ideally like to stay less than 10kg overall but I think that is challenging.
Most backpacks will have an

Small form factor builds have a funny way of turning simple upgrades into full redesigns
You start out wanting to change one fan or tidy up a cable, and somehow you're suddenly reconsidering the layout, cooling, GPU clearance, and half the case. That's part of the appeal of SFF builds, though. Every few millimeters matter, and even a small change can make the whole setup feel different.
I'm curious how many people here have a build that looks nothing like the original plan. What was the one change that made you rethink your entire setup?

Sffpc with a 9950x cpu
I used to have a itx board but damaged it by accident with a screwdriver and have used mAtx boards since. I have a 9950x which I need for heavy calculations which I now cool with a 280mm AIO which works okay. Also lately I do a lot of gaming on my steamdeck so I am not really using my 7800xt card. I am curious, what would be the smallest case with a short or no graphics card, but that can house a 280mm AIO? Or something that cools the 9950x cpu but not too noisy? I have Lian li B4 now. Thanks.

5L SFF Build in Vietnam – 7800X3D + RX 9060 XT – Looking for opinions + LP GPU source
I’m currently in Vietnam and putting together\~5L SFF PC.
• Case: Midori 5L-V2.4
• CPU: Ryzen 7 7800X3D – $285
• GPU: PowerColor Reaper RX 9060 XT 16GB (2-slot) – $652
• Motherboard: ASUS TUF Gaming B850I WiFi Neo – $257
• RAM: G.Skill Trident Z5 Neo RGB 32GB 6000 MHz – $474
• SSD: Kioxia Exceria Plus G3 2TB – $257
• PSU: FX600 Platinum 600W Flex-ATX – $166
• Cooler: Thermalright AXP90-X36 – $28
• Fans: 2x Thermalright TL-9015B – $23
Total: around $2,320
Does this look reasonable for a 5L 1440p build? Any suggestions to swap things maybe there’s clear way of cutting costs that I can’t see myself?
Maybe a smaller case available with similar spec fitment. If I would be able to source vastarmor than I’ll go zs d2 v4 unless someone suggest better smaller case.
Most importantly — does anyone have access to a Low Profile 9060 XT Vastarmor. The regular Reaper fits, but I’d prefer a proper LP card if possible. I’m in Vietnam so shipping from China or local sourcing would help.
Any feedback is appreciated. Thanks!

3 Options; New Psu, buy a full Aftermarket Custom Cables Kit or Just the cables i need.
So I recently did a pretty big system overhaul my thermals were tanking and gpu clearance was an issue. Still same 5800x3d on a Strix b550i, But I swapped cases Velka 7 > Jonplus I100 (things massive), Swapped GPU 6900xt > 9070xt. And upgraded the Ram and SSD 16 > 32, 1tb > 5tb(1+4) And new cooler from Alpenfohn Ridge > 240 AIO. Oh, the original build i bought for 900 which included Edifier 1280db, lg 27" 4k 144hz IPS, Wooting 60he, Razer Deathadder. hell of a deal. So doing my upgrade i was short 1x 8pin, i have 2x 8pins both w pigtails and 1 Sata Power/pigtail. I need 3x 8pins and an extra Sata Power for the 9070xt and the Asus Tuf ARGB PWM hub. Right now im using 1x 8pin and 1x 8pin + Pigtail for the GPU. And Only powering the PWM of the ARGB/PWM Hub.
So the question is Do i get only the custom cables i need for the CM V850, Get a full custom set, or get a new PSU, im thinking SF1000 from Corsair w atx 3.1.
Oh, I did order a case and cooler today, but wont be here til Dec. Ch170 Digital and Dpcool assassin vc elite. I got someone taking a boat overseas buying it and bringing it to me via Ship. Hence the mo+ delay.
Im leaning towards the new PSU only because I will be doing a full overhaul w the Rx10000 Gpu (getting the flagship model) and it comes with custom braided cables for easier management. but that's like 250. Can i even get custom sata power cables?
What do i do?

Building an ITX PC makes you appreciate every single millimeter of space
There's something strangely addictive about fitting a powerful PC into a case that looks like it shouldn't have enough room for anything. Every cable, fan, cooler, and component feels like a little puzzle, and one small change can make the whole build easier or turn it into a nightmare.
The finished setup is satisfying, but honestly, getting everything to fit without compromising airflow is half the fun.
For those who've built multiple SFF systems, what's one component or design choice that made your next build noticeably easier?

S300 internal power cable has the wrong handedness for the C13 plug?
I recently purchased an S300 case from amazon (link), but the IEC C13 to C14 cable has the wrong handedness for the PSU side.
To explain what I mean, the cable is has a left-handed right angle at the C13 plug, like this:
https://www.amazon.com/dp/B0B24ZD8TM?lv=shuf&channelId=704&ref\_=cm\_sw\_r\_apin\_dp\_G2P0QMEC0W66TVZ8TWVN&plpRedirect=mhFallback&th=1
By "handedness" I mean whether the cable extends to the left or the right after plugging into the PSU. With the left-handed cable I got, when the cable is plugged into the PSU, the cable extends to the right toward the motherboard, instead of to the left (to the front of the case, away from the motherboard).
https://preview.redd.it/qa1l9d2odg0i1.jpeg?width=4000&format=pjpg&auto=webp&s=5fe48ec0b34e71c86fb1517c012f4a6d057dd8a1
It seems what I need is a right-handed right angle at the C13 plug, like this:
https://www.amazon.com/dp/B0B24ZD8TM?lv=shuf&channelId=704&ref\_=cm\_sw\_r\_apin\_dp\_G2P0QMEC0W66TVZ8TWVN&plpRedirect=mhFallback&th=1
In other photos of S300, it seems like a right-handed plug is standard.
This is my first time building in this case. Does my S300 have an incorrect part, or is that how it should be?

empty weight of 1-2kg. Add in another 1kg for the monitor, and another 1-2kg for keyboard/mouse/controller/cables. Total will not be less than 13-14kg, probably 15kg.
Happy to hear thoughts of users who share similar requirements and how they tackled this.
I guess I will need to decide on components in the following order:
GPU -> Case -> Monitor -> Bag

Looking for SFF case recommendations (9–12L)
Hello everyone!
I'm looking for recommendations for an SFF case around 9–12L, preferably the one that does not look like a bucket.
should support either an SFX or SFX-L PSU and a dedicated GPU. I have no preference for the case layout. My budget is preferably under $120, and I'm open to ordering internationally.
Any suggestions are appreciated. Thanks!
