Well why not just sell your bitcoins and convert it to fiat then go visit the nearest computer parts shop. Because I think there are no shop that are doing this kind of transaction to ship computer parts all over the Asia as the parts of computer are very volatile so whenever that is going to be moved a little bit like hard disk, it will be destroyed.
If they are finding it difficult to purchase the spare parts, let them try using purse.io in case the products are not listed there, they can contact the admin directly and they will be very happy to assist by arranging required products by any means. I had many similar experience with them. Nice services, highly recommended.
