Amjad,
I agree with what Andrew says - you can buy some very powerful single
motherboard systems these days.
I would suggest two things though:
a) if you are planning to use this cluster for learning about MPI and
cluster interconnects why not get some gigabit ethernet cards plus a
gigabit switch?
b) Look for second hand Infiniband cards and a switch on eBay.
Or look at Colfax Direct sell http://www.colfaxdirect.com
I saw one of these rather nifty eigght port switches from Mellanox at Cloud
Expo in London:

Sweet!
Or even easier the twelve port version:
