I named my machines as groaningly as possible. My desktop is named Courtney (a combination of Core 2 and Tony). My apple laptop is simply "Roving Pear." This may be harder for a large network, but I bet you can manage.

Then in most cases, no. That's not the case. The vast majority of the time a judge won't let you get away with that. And FYI, there doesn't need to be a "breach of contract" section. If you violate a term of the contract, any term, no matter how slightly, you have breached. If you deliver 9,999.999 tonnes of steel when someone orders 10,000, you have breached. Minor breaches and major breaches are treated differently by the court and many aren't worth suing over. What you're probably thinking of is an indemnification clause - "If xyz happens, you have to cover court costs."

No, not if the original contract was written by a "good" lawyer. The fact is, there's nothing illegal about breaking a contract. The whole system of contracts is built on the premise that if the damages which will be awarded in breach to the other party are smaller than the cost of maintaining the contract you should feel free to breach. Breaching a contract is not breaking the law. So, if by "wiggle out of" you mean "breach", then yes. Typically the courts will attempt to hold you to the contract if at all possible or award damages for breach. It takes pretty big circumstances to actually void a contract.

(But minors can't legally execute contracts, can they?)

Actually, minors are fully capable of executing contracts, they simply have a backdoor out of them. When a minor reaches the age of majority, 18, they can renounce the contract unless the contract was for a "necessity." This should make adults wary of entering into contracts with minors, but there is nothing preventing a minor from forming a contractual agreement.

You're still missing the point. Just because I use a graphics card as an example doesn't mean the same rule can't hold true for other components. They still build their own systems, it's not like Dell suddenly took full control of their manufacturing process.
