A2SDi-8C-HLN4F are Mini-ITX so they fit in these: https://streacom.com/products/db1-fanless-mini-itx-case/ https://streacom.com/products/db1-fanless-mini-itx-case/ But you need to buy this GPU adapter: https://streacom.com/products/db4-gpu-cooling-kit/ https://streacom.com/products/db4-gpu-cooling-kit/ (for the small CPU) And buy M3 female-female spacers that are 50mm long and some M3 thread that you cut at the appropriate length. So it's a bit fiddly until they release proper small CPU adapters for these. Also to remove the heatsink that comes on the motherboard you need to run the board without fan until it heats enough to soften the heatpaste. Be careful to not rip the board when removing it, wooden icecream stick to bend might come useful.
