I'm planning to downsize from my ATX build to a small form factor (SFF) PC because I need something more portable for my work and gaming setup. Here are my current specs: I've got an RTX 4070 Super FE GPU, a Ryzen 9 9800X3D CPU, and a 4TB HDD. My budget for the new components is around $400.
I've come across a few parts that I think might work for my SFF build, but I'd love to get some feedback before I go ahead. Here's what I'm considering:
- Rosewill 750W ATX Power Supply
- Thermalright Aqua Elite 120 AIO Cooler
- Gigabyte A620I AX Motherboard
- Silverstone SG13 Case
My aim is to make this as compact as possible, and I also want it to be easy to move around since I switch between using it for work and gaming. Can anyone offer advice on whether these parts will be suitable for my current build?

Are you really using just a spinning HDD? If so, I highly recommend switching to at least a SATA SSD for your OS. It'll make your system feel way faster! About the cooler, a 120mm AIO is likely too small for your CPU—consider upgrading to something larger or going with an air cooler that'll fit in your case. And for the motherboard quality, avoid the A620 chipset; you should aim for at least a B650 for performance. Honestly, if I were you, I'd think about investing that $400 into a new chair instead of a downsized setup! What are your current specs for RAM and PSU?
I've built a few setups in the Silverstone SG13, and honestly, it's not the easiest when it comes to maintenance. You might want to check out the NR200; it's a bit roomier and easier to work with.
Don't limit yourself to the SG13; while it's small, it can restrict your hardware selection. Consider the Jonsbo C6 Max for a bit more room without a huge footprint. Here’s a better part list that fits your budget:
- **Thermalright Royal Knight CPU cooler** (better than the AIO)
- **MSI B850M-P WIFI motherboard**
- **Jonsbo C6 Max case** with a handle for portability
- 120mm fans for proper airflow
- High-quality 750W power supply.
This list will offer better cooling and expandability, all for around $350.
If you want portability, consider cases like the Hyte Revolt 3, which even has a handle! Just a heads-up, for many SFF builds, you might be better off with an SFX power supply. Also, a 240mm AIO would be much better for cooling that 9800X3D than a 120mm. If you're interested in the Revolt, just let me know and I can help with shipping!
