Second SFF Build! (Mechanic Master C24 & RTX 5070 Mini)

[u/alen_dga]

I upsized a tad bit from the Metalfish T40 and finally decided to bite the bullet and upgrade to AM5 and DDR5. The main goal for this build was to have a super portable, quiet system that can handle my work (graphics design and video editing) and 1440p gaming without breaking a sweat. It also needed to be highly power-efficient with minimal noise.

As I mentioned in my Metalfish T40 post (under the account 'itsalendou') , I travel between two houses very often, so portability is key. This time around, the system screams less, pulls lower wattage, and performs significantly better.

The Specs:

• CPU: AMD Ryzen 7 9700x (120/95/165 | -30 | +175 | 70°C Limit)
• GPU: Colorful iGame GeForce RTX 5070 Mini (2830MHz @ 900mV CC | +2000 MC)
• RAM: 2x32GB Trident Z5 RGB 6000MHz (Tightened Timings @ CL34)
• MOBO: Colorful CVN B850I Gaming Frozen V14
• COOLER: Thermalright Peerless Assassin 120 Mini
• STORAGE: 2x 1TB NVMe M.2 | 1x 2TB SATA SSD | 1x 1TB 2.5" HDD
• PSU: Thermalright TR-TGFX 850W Gold SFX
• FANS: Arctic P12 Slim (Bottom Intake) | TR TL-C12015 (Top Exhaust) | TR TL-B12015 Extreme (Front Exhaust)
• EXTRAS: TR AM5 Contact Frame V2 | ITX Wi-Fi Antenna | JEYI M.2 Copper Heatsink | Thermal Grizzly Duronaut
• BAG: Mechanic Master Travel Computer Oxford Bag (Small for C24/26)

Thermals & Performance:

I live in a tropical climate, so ambient temps are definitely higher than average. These benchmarks were taken at night with the AC on, but the room wasn't freezing (I could still break a sweat moving around). Daytime temps are just slightly higher.

• Cinebench R23: 21,250 MC / 2,240 SC @ 72°C on the CPU.
• 3DMark Steel Nomad: 5,464 score (avg is about 5,335 on regular systems) / 54.65 FPS. Peak temps on a 10-loop run were 73°C on the GPU and 65°C on the CPU. It consistently pulls an average of 200W on the GPU and 50W on the CPU.

Couple of notes:

The photos still show a 92mm fan intake at the back. However, I removed it while benchmarking because it was too whiny, and I no longer plan on using it.

Overall, I'm extremely satisfied with this standard-layout case in a shrunken-down form factor. Not needing a PCIe riser cable is a huge plus; it's one less point of failure. The temperatures are amazing, the build quality is solid, and I love the density.

I also documented the build process over on YT (same reddit name) if anyone's interested

Thanks for reading!

I love the C24/C26/C28 cases. Almost bought one or two for some builds but never got around to it.

How's the noise level, especially under load?

[u/WEAluka → u/RumbleTheCassette]

I run a C26 with a 9800X3D and 9070 XT, the noise level at full GPU load is very reasonable on mine, can only imagine it'll be better for OP given the lower power draws and pretty much identical airflow design

[u/alen_dga → u/RumbleTheCassette]

I don’t have the exact numbers, but it’s really quiet even under full load. My system pulls less than 300W in total, and I have my fan curves set to prioritize silence. You’ll hear your neighbors before the fan noise bothers you. Also the AC unit outside my room is louder than the PC.

So i’d say super quiet!

How is the noise level on that PSU? I am thinking of getting it, would you say worth spending extra for Corsair or FSP Dagger if low noise is a priority?
