Hi, I picked up an empty case HP Pavilion 6409.
According to the HP guide this unit was released in Asia Pacific (I am located in Singapore).
OEM spec Pentium II 400MHz, 64 MB SDRAM, 6.4 GB HDD, ATI RagePro AGP 8MB.
Aside from some yellowing on the grey plastic parts, the case is in good condition and I would not mind using it for a compact build.
It seems that HP may have used a small PSU. Indeed the PSU is probably not as deep as a standard ATX PSU. I also noticed that a standard 3.5" FDD does not fit in the case.
Checked on google but could not find any internal pics or teardown that would reveal the parts used for the OEM build.

If someone could point out to suitable PSU and FDD for this build?
Thanks
