If it is a R4k Indigo you can feed it with PS/2 parity FPM RAM. (It
needs four identical pieces per bank.) A R3k Indigo needs special SGI
You can connect external drives if there are no sleds.
What you believe to be the motherboard may be the graphics system.
Remember that a "real" SGI machine is a keyboard processor (typical a
MIPS Rxxxx thing) with a graphics system. Depending on the type of
graphics it can be normal that there are empty sockets. (You may end up
with only one graphics processor instead of four, no Z buffer, only VRAM
for 8 bit color or the like.) But even with only one graphics processor
you get a decent graphics performance. Remember that it is a SGI. :-)

Yes. The Indigo PSU is error-prone[1], so my advice is get it at least
for the PSU. If you don't get it, you will get a offer for a full loaded
Indigo R4k Elan with dead PSU next week. ;-)

[1] We had six Indigos at the Unix-AG. Five of them have now dead PSUs.
