I run a small dedicated box for my business site, as well as one Xenforo install and a couple of other smaller sites. I think there are 10 sites in total in a LAMP environment. A few of them are running WordPress, but nothing real resource intense.
Dual Core AMD Opteron(tm) Processor 180
Raptor 10k Drive
Any suggestions on CPU/motherboard/memory? I have a SSD that will go in the new machine. I would like to keep the power consumption low, and don't need a speed demon. I have a new i5 3570k sitting here, but was contemplating selling that, and buying an i3. Cost wise, I would like to keep the build in the $200 range, considering I wont need a PSU, case, drives, etc.
I was thinking the i5 is a bit over kill. Anyone have experience with Atom based machines for hosting? The power savings would add up over time... The load on my Opteron never averages above .12, which is why I thought the i5 would be a bit much.
I'm using a Pentium G3220 Haswell chip in my storage server at home with ECC RAM. Based on what you've said here, I think something like that would completely destroy your existing workload. The chip is usually around $70, which might fit nicely into your budget. A server board for ECC would likely be outside your budget, but cheaper desktop boards would probably work just fine. Something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128662
A Haswell chip like that would also likely cut your power consumption considerably. With 16 GB of RAM, 3 x 3 TB HDDs, a 120 GB SSD, and a 24 port network switch, I'm only drawing about 50W of power.
