Not in the general scheme of things. Yes memory types and motherboard do 
affect the general running of any box but it's what you accept. The 
machines I already have are crappy bits of junk lying around.

LOL Quite.

Yes but I think I can afford to spend a grand on my system as apposed to 
one of those for all the bad aspects of why I'm doing this.

This is OpenMOSIX, in fact you can download the Knoppix version and just 
sling the CD into all your nodes and have a cluster on demand. I have a 
few CDs if anyone wants to give this ago at the next meet? Might be 
handy. I can show a Blender model and then we can play with a render 
farm straight after!
