I have run my home Lustre server in a single "whitebox PC" for many years (filesystem originally formatted with Lustre 1.4 in 2006 and has been upgraded in-place ever since then). I have 1 MDT + 5 OSTs (one OST per drive), using LVM below the filesystems to facilitate snapshots for MDT backup, and to allow LV migration to new drives as they become full/old. I started with maybe 2 or 3 200/300GB drives, and now have 3x 4TB drives and 2x 6TB drives + 512 GB SSD for the mDT. The server itself was a Pentium-D + 2GB RAM for many years until that hardware failed last yeaar, and is now a 3.3GHz Core2-Duo + 4GB RAM (old Dell deskside computer). Basically, any computer you can buy today is going to be enough for functional testing, if you aren't looking for peak performance. Client performance is limited by the 1Gbit Ethernet I'm using, but that is enough for my use (video is under 1MB/s, and backup of family laptops). I have a beefier x86 client (i5-6600 + 48GB RAM), formerly an Intel Atom, but that couldn't handle HD video decoding. I was also running a 32-bit Raspberry Pi 3 for a while, but it was very marginal for HD video and died after a year of uptime.

[lustre-discuss] [EXTERNAL] Hardware advice for homelab
I have not done this myself. But it might be worth your while to look into options like Linode to rent out some cloud time. Lower TCO and lower setup time.
