I've been trying to Google this and reading through older posts in the forums here, but I've come up with surprisingly little. Maybe I just suck at searching. Anyway, I'm wondering what the downsides of using a G5 tower for a light-duty server would be. The most obvious question is whether you can boot the tower headless--I remember that being something of an issue back when, but perhaps it's not a problem now? I also know the xServe will have beefier components (ECC RAM in particular), but considering how much cheaper the Applecare is for a tower, and if the hot-swapability of the drives isn't an issue, a PowerMac would come out a lot cheaper than the Xserve, it would seem. Given that my total budget is around $4000 (and that has to include switches and other hardware), I'm having a tough time deciding. Edu price of single G5 xServe w/512MB RAM, 2X250GB HD, graphics card (just to get it set up) = $3,309 Single 1.8G5 w/same stats, OSX Server Unlimited = $2,271 (and I could save another $150 by buying the drives myself from ZipZoomFly) Add in 3 years of maintenance and the xServe is $560 more (though that service is onsite). So, if density isn't a huge issue, and I'm not dealing with anything that requires a lot of power (office fileserver, maybe distributed home folders) is it really worth spending $1000 more and probably having to forgo the extended warranty for the xServe?
