keep the hard drive
sell the rest for whatever u can
got a job? if not get one
use funds from old parts + wage/savings to buy a funkeh nuu system
alternativley, squeeze the system into a smaller space you can, buy a touchscreen and bam youve got an entry level carpc on wich to devote countless man hours developing your skills in car pc'ing

or general computer stuffs, whatever tickles your fancy really
All the best
