Over the past few days I have come to realize you might either;
1. Get an overkill server at a high price for capacity you don't necessarily require
2. Get overpriced server for specs that are rubbish
It is better to give a detailed description of what duty server is going to carry out.
The price of 600GB NL SAS 10K 6Gbps HDD is higher than a 1TB 7200rpm SATA HDD which both can fit into the server.
If you get a proper sales person they should be able to advice you properly on your needs and you end up saving $$
and by the way 8GB ni kidogo.
