Basically, it breaks down like this:

CAT5 is rated upto 100Mbps
CAT5e is rated upto 1000Mbps
CAT6 not sure, but if you want minimal packet loss etc at 1000Mbps, this is
the way to go.

This is the cable rating btw, in case you don't know.

As regards hardware, the Sun gigaswift cards aint too expensive, especially
on ebay.

They're two different gigabit media.  'Copper' is RJ-45 plugs on a
Cat-5e/Cat-6 cable; 'fiber' is an older fiber optic medium that probably
isn't of much interest to you.

Probably.  Gigabit uses more (all?) of the wire pairs in Cat-5 cable, so
unless they were wired on the cheap (or done to carry 100BaseT and phone
over the same cable) they should work.

Have you checked http://sunsolve.sun.com?  A quick perusal points to X4150A.
