Extending CAT5

[{{INX}}]

Can anyone advise the best way to extend Cat5 cabling?

I cabled my whole house when we first bought it a few years back and the wires cannot be changed but I now need to relocate my server and Gigabit switch.
Are couplers or punchdowns the best option for roughly 16 cables?

Thanks for the quick reply. I was leaning more towards punch down, but can you get multiple blocks rather than individuals?
