Does anyone know of an aftermarket case manufacturer that will hold a Compaq
MB?

I have a Presario 7970 (Athlon 700mhz) that needs a new power supply, I was
thinking about putting it in a smaller tower while I was at it (it's no
longer my primary pc, just a 2nd computer in a guest room). I read that
Compaq uses proprietary MBs. Compaq confirmed this and told me to contact a
Compaq Authorized Service Center to buy a new Compaq box of different size.

Any other sources or suggestions?

Thanks
