WOW very nice. I had not mentioned that I was hoping to keep the price down. The laptops I use, were bought on sale for under $400 each.
When I posed the question, I was thinking in that range.
My desktop is a Pavilion g6 running a AMD A4-3300 APU @ 1.9Ghtz and 4 Gig RAM. My LAMP Dev server is a HP G61 HP G61-320US I think it has 3Gig RAM and and not so powerful AMD also. (both are laptops) I made this move to see if my home office would be cooler during the summer and it has made a big difference. Now with the E520 (mentioned below) my office is noticeably hotter.
I decided to move my two low traffic websites to a server in my home office using my Cox Business account because of poor service at HostGator. I feel I can do a better job and will probably learn a lot doing this project.
At this point I am using an old Dell E520 that was my old desktop until last year. If this experiment works out I will want to buy or build a server. I am on a shoestring though.
If either of these sites were to get any real and sustainable traffic I would rent a server. It seems it is less costly to rent a server than to co-lo. And the data center is responsible for the hardware. Much better deal. This is assuming I would be making enough off these websites to justify the additional expense.
Thank you so much Harry for all your help!!

Hi,
I am not finding that specific intel processor on any boards
easily... The only real board I am finding is a supermicro
X9SBAA-F, which seems to be in the ~$250 ish if you can find it.
A dual core (65watt max) AM3 processor will easily be faster then
the Atom. And quite possibly lower overall power, since it will
be in idle mode more then the Atom.
This is more then over kill for what you are doing, and could
easily be cut down.
The chassis must have either a fanless PSU or a PSU with a rear
fan (not side)

Total with shipping is under $850, I left out an optical drive,
but there is physical space to put one in if needed

Wow what an
interesting thread.
Thank you to everyone.
Here are some of the points:
1) The downside of a laptop is the issue of durability and
maintainability. IME, they just aren't designed for long
life.
And, aren't (as) easy to repair/replace (components) when
they
*do* break.
2) Lack of ECC memory
3) Lack of redundant hard disk drives
4) Personally I would probably look at either the HP
Microservers, or build something low power based on AM3+
cpus and ECC memory.
5) Look for an 80+ silver or gold PSU, and the power usage
should be similar to a laptop.
6) HP's Microservers are great hardware, and frequently
can be found <$300 on sale.
7) AM3 stuff tend not to be low powered generally, unless
you get into dual core.
8) If you are really power concerned you might consider an
Atom server processor
Alternatively Intel makes both a 17* and a 20 watt Xeon E3
9) SSDs
10)
http://ark.intel.com/products/71267/Intel-Atom-Processor-S1260-1MB-Cache-2_00-GHz
2 cores, 4 threads, up to 8G Ram, 8.5 watt, and only $65
retail. It even has Intel® Virtualization Technology
(VT-x)
I had not thought about ECC in years. Maybe over 10
years. Not sure If I will in the future. Checked with
the data center where the servers are that I do my work
on. The data center owner said divers and power supplies
were his main issue not ECC. He said ECC can be an issue,
however from his experience ECC memory is not worth the
gain realized.
What made me thing was the question "What do you do with
the info?". I have no answer.
I had not thought about building a low power server. That
would be the best of both worlds. I may do that. Not as
much fun as using a NetBook running an Atom n2600 with 1G
RAM. That would be a cool project however given the
processor runs at 1.6Ghtz and the drive runs at 5400 rpm,
that might not be a long term solution for hosting a
couple WordPress websites. Cool project though.
I was very intrigued by
http://ark.intel.com/products/71267/Intel-Atom-Processor-S1260-1MB-Cache-2_00-GHz
2 cores, 4 threads, up to 8G Ram, 8.5 watt, and only $65
retail. It even has Intel® Virtualization Technology
(VT-x)
My question would be, would it be wise to run SSDs on a
web server? I'm sure that would make for a much faster
server and much less heat, however is that a viable
solution at this time?
Thank you all for a very interesting thread!!
