I am looking at a new build.

I have two older Antec Cases (probably about 6 years old, Sonata and some tower case) Both are in good condition, I would like to use these cases in my new build to save some cash.

The problem is I think the power supply will be two small (currently only around 450Watts) I plan to build a Core i7 system, with decent graphics cababilities.

Really dumb question, but will newer power supplies fit inside one of these cases? Or should I just buy a new case and power supply.

What size type of power supply is good these days?

Many thanks.
