PCI riser card help needed! Please HELP!

[pepelaz]

I have a very urgent problem.
I need to fit 3 cards into the 2U rack case.
The mobo is dual athlon with 64bit pci, 32bit pci and AGP

Cards:
Lan - 32bit 33MHz PCI (standard or low profile)
RAID - 32bit 66MHZ! PCI (standard)
video - 32bit 33 mhz PCI standard OR AGP low profile

What risers do I need to fit it into that case/mobo?
Will one 3in1 64bit riser work for all 3 pci cards?

As far as I understand, 32bit 66MHza pci should go into a 64bit slot, but does it need a 64 bit riser for that?

can 32 bit cards go into 64 bit risers/slots?

Please, tell me what will be the optimal configuretion and what risers I have to order.
I'm desperate - I need the system up by Monday.

Thanks in advance.

What type of machine is this ?

Doesn't sound like a Compaq(HP) (Athlon processors ?)..

Do you have a motherboard model no / manufacturer ?
