Regarding the model above, I'd like to ask a few questions:

1) What speed is the 4GB RAM?
2) What speed is the 500GB HDD?
3) Is the W7HB 32bit or 64bit?
4) Do you provide trade-ins and replacements, for example, I would like to purchase an upgrade of the RAM to 8GB RAM. Is it possible?
5) What about upgrading to SSD? The price you've given is an upgrade price or stand-alone product price?
6) Any other free gifts with this purchase?
7) How much for postage to Putrajaya?

Thanks for your time!
