All right lets make one:
Get all the above config except:
the cabinet: Make a wall crawler (Just google it I read about it somewhere)
the speaker: get a simple earphone approx Rs.10
the HDD: go to Kenya or someplace where they still sell 4GB HDD.
the motherboard: get a P1 and mobo which supports, should be available in all leading stores.
and what else... yeah the monitor.... I think black and white is still manufactured somewhere.
Total ~5.21 (Kenyan Dollar)
Sorry about total sarcasm. Couldn't help it. Up the limit by atleast 5K. Then help is available everywhere.
