[CentOS] G4-400mhz enough for CentOS 4.3?

It's that time again.  I'm stuck with a bunch of older Powermac G4's 
that I either need to repurpose or give the heave ho.  I've not tried 
CentOS on Mac hardware before.  Would the following config be suitable 
for a (somewhat slow) workstation?

PowerMac G4
400mhz
256mb RAM
40gig ATA disk
Some sort of dual-head ATI video setup with 64mb VRAM (I've forgotten 
which cards they are)

Cheers,
