Can i keep old pc parts for new motherboard?

I was just wondering if it was possible to keep my old sound card, i think its a network card, hard drive and cd drive and put it onto a new motherboard?123456monster

PCI cards, hard drives, CD and DVD drives, peripherals, cables, and the power supply can all be ported to a new PC. You will need to check your memory type to see if it's compatible (older PC133 memory is not usually compatible with new DDR2 PCs). You processor and heatsink are also likely to have to get tossed.

You graphics card may be portable depending on if the old one is a PCI Express or AGP slot card. You'll have to check. 

Keep in mind an old power supply may be insufficient for today's PC demands.

Well this is what im trying to get

AMD Athlon 64 X2 Dual Core 4200+ 2.20GHz (Socket AM2)
