Network config possible?

[odin]

This is our current houselan:

CABLEMODEM
             |
GATEWAY (linux box)
             |
  __ HUB__________
 |          |         |                |
PC1   PC2  AMIGA   PC3

God, I really am a l33t ASCII artis ;-).
-edit- BAH, no non-proportional fonts here?

Ahem,  I want to change it to this:

CABLEMODEM
             |
GATEWAY (linux box)
             |
  __ HUB___
 |          |         |      
HUB  PC2  PC1
 /   |    \
AMIGA PC3 PC4

Is this at all possible? In particular connecting the two HUBs together. I want to save myself pulling a *3rd* UTP cable to my room, you see :-).

Thanks guys,

@Fluffy:

Well a HUB costs 30EUR at my local PC-whore, and a router 70EUR.

Still a significant difference =).
