2 Old PCs (Incomplete) (Rowledge Nr Farnham)

2 old PCs, neither have HDDs or DVD drives. The Small one has a working motherboard with Intel Atom 330 @1.6Ghz, the PSU is suspect.

The larger one is a MSI K9N6PGm"-V motherboard with AMD Athlon X2 4200+, working but CMOS battery flat. 400W PSU working. Useful Tower case - but no side.

Any use for parts or to run old programs?
