okay so i want to speed up my server a bit, right now it's a PM G4 (agp graphics) 350MHz, 704MB ram. I'm torn between a G4 upgrade (to around 1GHz, there's one on sale on fastmac.com for 159), a RAM upgrade (going to a gig or 1.2gb), or a hard drive upgrade (I have 120GB 7200rpm drive, thinking of making a RAID with another drive). so what will be most beneficial to my server speed? I occasionally use the powermac for other things, but not a lot (I have my powerbook for that). I serve mainly static pages, but I have a growing mysql database for my stock photo gallery . Any advice would be useful, so Thanks in advance!
