This seems like a worthy cause.
@Jacen Li if you have no storage I'll provide that.
depending on what your chassis can handle - would need to know bay count form factor, and preference:
SFF: some 500gb sata spinners - consumer grade.
SFF: a couple of 480gb ssd's - consumer grade.
SFF: a couple of 600GB 10K SAS spinners - enterprise grade.
LFF: a couple of SATA 1TB or 2TB - prosumer grade.
NVME: a couple of 256GB nvme m.2 80 - consumer grade.
you'd have to scrounge for pcie to nvme adapters though I might have one floating around I can spare.
