Hi all, I have 31 computer which need speeding up. 
Some pics so you know what I'm dealing with:
		
		
	
	
		
	 
		
	 
		
	
Current specs are:
A rubbish AOpen socket 478 motherboard
Celeron 2.0ghz (some do have 2.4ghz)
512mb RAM (2x 256mb RAM)
40gb IDE HDDs
160W PSU
M-ATX chassis
I want to spend the smallest amount possible, with the least amount of effort to make these better.
First option: Upgrade to Pentium 4 and replace a 256mb RAM module with 1gb.
I have actually tried this and it has made quite a different but it would cost around £60 per computer (£1860 for all 31) which seems like a lot to spend on a computer of this age.
Second option: Get this:
		
	
Will 160W be good enough for this, have I made any mistakes?
Do you have any other good ideas?
Thanks
