I realized I forgot to include a parts list for the cluster in my ARM cluster post (all prices are as of March 3rd, 2019), so here we go.
- Three Odroid HC2 ARM SBCs @ $54.95 each. These have gigabit ethernet ports, a SATA-3 port for 3.5 inch or 2.5 inch HDD/SSD drives, Samsung Exynos5422 Cortex-A15 2Ghz and Cortex-A7 Octa core 32bit ARM CPUs, with four 2GHz cores and four 1.4GHz cores and a UHS-1 compatible microSD slot that supports up to 128GB/SDXC.
- Three 12V/2A Power supplies @ $5.95 each and three power cords for the Odroids (They’re sold separately) @ $1.95
- Three microSD cards - I used some I had already - they’re cheap, so get at least 32GB though 16GB works too.
- One 8 port Ubiquiti UniFi Switch 8 60W (US-8-60W) @ $109.59, though really any gigabit switch will do.
I didn’t bother with cases for mine, I wanted to maximize airflow since they don’t have onboard fans.
