Best modular expansion cards for Framework Desktop builds?

- +1 to what was said earlier!
- honestly, just use the Framework USB-C Expansion Card and a cheap Anker 341 USB-C Hub (7-in-1).
- it's way cheaper and runs way cooler. gl!

Seconding the recommendation above. Honestly, I've had issues with heat buildup using too many high-draw cards at once, and it kinda makes me worry about long-term stability for a desktop. I'd skip the bulky ethernet card and go with a Sabrent USB Type-C to 2.5 Gigabit Ethernet Adapter instead. It's way more reliable for a permanent setup and keeps the heat away from your Mainboard. Plus, if you need that MicroSD slot, the SanDisk Professional PRO-READER Multi-Card is much safer for fast transfers than those tiny expansion cards that get super hot. Better to be safe, ya know? gl!

Since youre going for a full-on desktop conversion, you should really think about how to maximize the internal headers rather than just the four expansion slots. If you want that clean desk, you should look at internal storage expansion vs dedicated audio modules for your IO.

• Framework 1TB Storage Expansion Card

Pros: High-speed NVMe-like performance for a scratch drive or a secondary OS. Cons: It gets TOASTY during sustained workloads, so you need decent airflow in your enclosure.

• Framework Audio Expansion Card

Pros: Great for relocating your headphone jack to the front or side of your build for better cable management. Cons: Its a basic DAC, so dont expect it to drive high-impedance studio cans without an amp. Anyway, if you really want to lean into the DIY spirit, I'd suggest printing a custom VESA mount shell. It lets you hide the whole Mainboard behind your screen and organizes the cables way better than the stock plastic case. Their are plenty of files on Printables that offer better cooling than the official Framework stuff, which helps if youre using those high-speed storage cards.

Honestly, I've been running a Mainboard setup for over two years now and it's been a journey. Most people dont realize that these expansion cards are basically just tiny dongles, so stacking too many high-power ones like the Ethernet card actually creates a lot of unnecessary heat and bulk in a small enclosure. I had issues with my initial build cuz the Ethernet card was literally drawing power even when the system was supposed to be sleeping, which is super annoying for a permanent workstation.

For your situation, I would suggest:
- Stick with a DisplayPort card for your monitor. I've found them way more stable than HDMI for high-refresh rates over the long term.
- Just get any USB-C expansion from the Framework store and use those for almost everything.
- Skip the MicroSD card internally; it's honestly not as good as expected for high-speed transfers and just adds clutter.

Basically, keeping the I/O simple on the board and offloading the heavy lifting to a powered dock is way better. It keeps the thermals in check and avoids that messy look. gl!

For your situation, I'd honestly suggest being pretty selective because the 'dongle' nature of these cards can be a bit of a letdown if you're expecting native desktop performance. I've been messing with these Mainboards for a bit, and unfortunately, the Framework Ethernet Expansion Card is kinda bulky and tends to run warm since it's basically a Realtek controller crammed into a tiny space.

If you want a clean desk, I'd skip the MicroSD card and just keep a couple of Framework USB-C Expansion Cards as your baseline. Then, if you really need speed for your camera, just plug in a dedicated SanDisk Extreme PRO USB 3.2 Type-C Flash Drive or a high-end reader when you need it. Highkey, the most essential card is probably the Framework HDMI (2b) Expansion Card for that monitor setup, but stick to USB-C for everything else to keep the heat down. It's not as good as expected if you fill all four slots with high-power modules tbh...
