so i bought the 1000ft pack of cat5e cable with 100 crimps and a crimper and network tester. i'm planning on rewiring my entire house's cat5 lines. while i was checking my existing wires, i noticed that some were straight through and some were crossover. now i know that pc to router can use straight through but router to switch or w/e needs crossover. so my question is, can i just use crossover for my entire house and just skip the straight thru?

a better idea is to have ALL wall wiring be straight through.  all of it.
Create tails that are crossovers when needed.  you can connect a crossover cable to the wall that is straight through and effective cabling in crossover.
This way you still have options at all ends and flexibility.

BBYF16,

You want to just run the strait through wires for that job.  Crossover cable is ok for connecting 2 pc's, but after that, you should run strait through cable to avoid any troubleshooting headaches down the road.  I would not advise that.

You would need a crossover for PC<->router, and NOT for PC<->switch, exactly the opposite of what you've said.

Normal building wiring practice is for remote jacks to be wired staright through to a central "patch panel".

Chad's suggestion of crossover tails is excellent -- it's what we do here.  Technically, it violates spec, but it solves a lot more problems than it ever creates.
