Personally, I'm not sure.
I sent a message to a seller making enquiries about a £600 computer.
I asked ...... Hi guys,
I just need to check these things to see if I need to buy stuff elsewhere before buying your PC. Can you swap the keyboard and mouse that you supply for wireless versions of both? Also, can you provide a restore disc that can be used to bring the PC back to its current state.
If the answer is "YES" to those questions, please let me know a total cost and I'll have one and pay just as soon as I know the price.
Cheers,
Steve
The reply came back ......It will be normal USB keyboard mice and wireless USB adapter so no need cable to connect with router.
The seller is obviously not the full shilling (As we say in these parts) so I bought one elsewhere. His loss.
