If want to resurrect that system, get another 775 / ddr2 board while they are still available, here is a decent one
BIOSTAR T41 HD LGA 775 Intel G41 $60 free shipping
and do the linux install will be decent. Replace the PSU while you are at it, the apevia / aspire power supplies are junk and can hardly handle 1/2 of what it stated on the label. Get one of these...
COOLER MASTER GX 450W RS450 $45 + $2 shipping & $10 MIR
Rosewill Green Series RG430-S12 430W $45 + free shipping ($20 instant)
CORSAIR Builder Series CX430 V2 430W $45 + $2 shipping ($5 instant and $10 MIR)
pretty good deals and much better quality than the one you have.
You can re-use that case, IMO they are meh quality, not the greatest airflow for sure - the newer bottom-psu mounted ones offer much better cooling capacity, and 120mm fans make it a quiet task. Here are a couple I posted earlier for reference
HEC Blitz Black Steel Edition ATX Mid Tower $40 w/ free shipping ($25 instant) ** excellent deal (I would pick this one, pretty sturdy case)
COOLER MASTER Elite 311 $45 w/ free shipping (one of the standard cases I use in budget builds)
cheers
