It depends if all your networking devices are gigabit speed.  Then there is no advantage to go cat6 if you cannot use gigabit speed.

If all your networking hardware is gigabit capable, Cat6 will give your network gigabit speed and be "certified" for gigabit speed.

Check the specs for those Dell Powerconnects, I'm sure they will have a gigabit network connections.  I would not buy this unit here at this link.

If your switch can only doing 100mbs then use CAT5e, CAT6 will be waste of money since the switch will bottle neck your network to the lower 100mbs speed.

how much is invest in cat6 vs cat5e cabling ? thinking only in the cable costs?

SommerblinkCommented:
Cat5e is still rated for 1Gb speeds.

The killer for network cabling is usually the installer.

Things like maintaining a 6" gap between your cable and your electrical runs (provided it’s in conduit. If it is not in conduit, then you must maintain a 12” gap) for every 120 volts. Example: if you have a 240V line, then you must maintain a 12” gap if in conduit, and a 24” gap if not. Also, this especially goes for running parellal to electrical lines.

If you run perpendicular, you can run closer… but again, try to maintain your distance.

Draping your cabling over florescent lights. BIG NONO. Keep all your cabling at least 24” away from any florescent energy source.

Next place for signal loss… in the termination. Doesn’t mean you need to go all out and buy the most expensive patch panels or jacks. Just make sure they are from a reputable source and you have a good termination tool with a newer punchdown bit.

Final thing. DO NOT MAKE YOUR OWN PATCH CORDS! Seriously. You can buy good quality patch cords for far less than the time it will take for you to make them yourself. There is no savings in making your own. Seriously! :)

ooh, man so good advices, but i want to try into utp6, how much increase the cost in terms of the lyer?

It is dependent on the cabling company.  Some have higher mark ups than other companies.  Get price quotes from three different companies and you will see who is the most expensive.

what happend if my printer's nics are 100BaseT, all the network go down to 100 baseT,? even all the pc and switches are gbit?

No, your gigabit network devices will still communicate to other gigabit devices at gigabit speeds. When they speak to a 100 Mb network or even a 10Mb network, network flow controls will kick in which will allow the faster speed devices from overloading the slower devices.
