I'd guess the hard drive would still be okay, so someone with a bit of savvy could remove it and retrieve your stuff if you don't feel up to the job. It's an easy matter to buy an external caddy for a 2.5" drive - but be sure whether it's PATA or SATA first, or find a caddy that will handle both.

I've got a little 'magic box' that plugs into the PC via USB, and has connectors and power for all three types - 3.5" PATA, 2.5" PATA and SATA (which is identical on both 3.5" and 2,5" drives). The only make/model on it is MIDTE and I've had it quite a while...

I've found a seller here, so you may be able to track one down...
