Hit or miss, honestly. It varies with different parts for different models. There are some for $70 BIN on ebay, plus $10 shipping. Much cheaper than building a new system (even after the parts you could move over - HDD, Ram, CPU). Of course, *your* priorities will determine how you spend your money - are you happy with your system now, or is it worth the time/money to build another?. Keep in mind that the current Windows install is directly tied to a Dell system and it cannot be transferred over, so if you decide to buy new parts and do a budget system, you'll need an OS.
