Wow, if you got those for free
, nice find!
Uses a PCIe x16 slot for video. Part out $43 for a 6450
? [This one is fanless, has a 5 yr warranty and uses 18W max. on the +12V rail] You can get lesser rez for around $30 or a refurb. Or use an old card if you have it.
Same with a monitor, use an old one or buy a cheapie.
You don't really care about much since you won't use video much.
You can also try a thrift/second hand store or swap meet/yard sale.drivers
Might not want to update the BIOS however without a backup. Weird huh
