I was going to attempt the Project PowerMac G5/X86 done by Mr Bean. In his mod he used aluminium as a motherboard tray since the standoffs differed on the G5. I had some trouble finding an aluminium sheet at my local hardware store but I did find a steel sheet instead.... so basically I was wondering if its alright to use steel as a motherboard tray instead of aluminium? Are there any cons to it? Will it effect the system performance at all? (I don't see how it could but thought I should ask to be safe) Thanks in advance.
