use old psu or case from hp compaq elite 8000 for atx motherboard?

[jalikaria24]

hello i have a hp compaq elite 8000 pc, its the normal form factor one, like regular desktop sized. its not the small one.

i recently got a good used deal on a asusP8P67 PRO with ram and cpu together,

the mobo is 

ATX Form Factor
12 inch x 9.6 inch ( 30.5 cm x 24.4 cm )

and the power requirements are:

For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version) 

Do not forget to connect the 4-pin/8-pin EATX12 V power plug; otherwise, the system will not boot.

so i think it needs the main 24 pin connector and the 4/8 pin eatx12v power plug.

i am not gaming btw!

i assume not but testing my luck

1. any possibility i can use the case for this motherboard? or is the mobo too big / the connectors for the case are properiety?

2. any possibility i can use the 320w(i think thats the rating) psu that comes with this case? or doesnt have proper connectors

thx

@jalikaria24,

The entire motherboard and power supply connections are HP proprietary.

I call it a 6 x 4 board. The is no conventional ATX 24 pin main power header.
