Replace Celeron with Pentium 4

The best thing for determining what you can do is the motherboard manual. Do you have one for you HP PC ?
The HP website says that the 503n uses the 845GL chipset. This is an Intel chipset that apprently supports 400Mhz front side bus (FSB) Celerons and Pentium 4s, so you should be able to purchase any Pentium 4 that uses an FSB at 400Mhz.
Now I would take that with a grain of salt. It may be that the 485GL does not accept working with a CPU at more than 2.8Ghz (since Intel specifies that the Celerons with 400Mhz FSBs can work at frequencies between 1.7 to 2.8Ghz). On the other hand, it may also be that fastest Intel CPUs no longer work with a 400Mhz FSB (they're up to 800Mhz now).
You also have to pay attention to the packaging of the chip. Your celeron uses an FCPGA with 478 pins (the traditional pins under the CPU), so you'll need a P4 with the same pins and pin count.
Hope this helps,
Pascal.

Infact if this is a 845G chipset based motherboard it will almost definately support, not only 400 but 533fsb processors as well.
As with all upgrades of this type, your motherboard is likely to require a bios flash to recognise the faster chip, this flash should be available from the HP site.
If you are lucky, some retailers still have socket 478 P4's on the shelf (old stock)
But be careful! first you need to establish what the latest HP flash will support and as a side note* a suitable CPU is likely to be PRE PRESCOTT! (Northwood or earlier)
Found this 2.4 533 on newegg
Just in case you are wondering, a 2.4 P4 533 represents a considerable performance increase over a CUT DOWN Celeron 1.7! but comes at a low budget price.
Check to make sure you have PC133 or PC2100 (or above)memory if going 533fsb (you should have going by the age)
