I am considering upgrading my HP Pavilion 4535 (400 MHz Celeron, ASUS/
HP Hawk motherboard- Micro ATX, 256 MB RAM, 30 GB 5400 RPM HDD).
Considering the following:

- AMD 64 processor with 90 nm core
- Socket 939 board
- 2x512 MB DDR RAM
- 7200 RPM SATA HDD

What are the possible issues if I decide to replace the guts, but keep
everything else in my existing machine?:

- Will the existing HP 4535 case hold a standard ATX board? The current
one is Micro ATX, I think.
- Will the existing power supply be able to power the new chip?
- Will the existing case allow the new chip to cool. Do I need a new
fan?
- Other issues?

Should I just scrap the existing case and buy a new case and power
supply?

Thanks for the help

The existing HP chassis has a microATX board in it, and it cannot hold a larger
full ATX board. Any modern AMD (Semperon, etc) or Intel processor (Socket 478
Celeron or Pentium 4) requires a power supply which supplies 12v direct to the
motherboard via an additional power cable. Your system has an older ATX power
supply which lacks the 12v power cable, and is likely to come up short in
supplying the wattage needed by a new motherboard, CPU, memory and SATA drive.
You also need different power for an SATA drive than for an IDE/ATA drive.

All of the above argues for a new case with power supply capable of powering the
newer motherboard and SATA drive. 300w is a minimum, 350w better... Ben Myers

In addition, frankly the HP microATX Pavilion cases are a royal pain in the ass
for maintenance, upgrading, and access to all the devices inside... Ben Myers
