Well, its do-able by hand, but it depends on the package type. You can't resolder BGA packs without special tools.

Get a small hot-air gun for desoldering, one of the little "gas powered" soldering irons usually has a hot gas adapter - they work best.

A VERY fine iron is ideal for resoldering, if you use solder wire, if you use solder paste (which is applied by a syringe, run a thin line of paste down ALL the pads, at right angles, drop on the package, and then evenly heat with your hot air gun

The last time I hand-soldered on a mobo was when I upgraded my IBM-PC from 16K to 64K (yep, K - not M, not G, but K) of RAM and it was a royal PITA even with the DIP spacing. Soldering on a multilayer PCB is not for most DIYers; it requires special equipment and a lot of practice. Ie, if ya gotta ask, don't do it.
