Dave,
Are you actually proposing to get 4 different machine configuations?
Given that one can buy 1U dual Xeon/2 Gbyte boxes for not much more than
1K+VAT, there doesn't seem much point in buying different hardware
configuations, unless you want to include a box with a RAID chasis.
I think you should get any machines with 3 year warranty (either on-site
, or supplier collects at their expense)
