Headless Computer:

Is it without a monitor, keyboard and mouse? How do you get it setup? How do you shut it down? I assume it will just be running seti/lunatics/win8.1.

Either you have to have to have a really good memory, or you have to at least begin with a monitor.

You can set-up something like TeamViewer or Real VNC on it so that you can log into it over the internet / network. Shutting it down is easy enough if you set it to shut down if you push the power button (and hold it less than 4 seconds).

if you're planning on keeping it headless, why pay for a windows license. You can install linux on it and keep a minimum installation, enough to get boinc running and ssh to access it. In that case, you can try hamachi, where you can run it of few computers and have them connected in some sort of VPN.

There are many options. A few are.
1) You could get an inexpensive KVM switch to go between your machines.
2) Get a network KVM device so you remote into it and have full control over the whole machine just like a KVM, but across the network. However these are often expensive.
3) Connect your current monitor and input devices. Setup the system and install remote software such as VNC when done.
4) Connect your current monitor and input devices. Setup the system then control it remotely over the network with command line options.

I mostly do 3 or 4 myself.
Once you have the system setup & configure BOINC to launch on start up you can control BOINC through BOINC Manager from your main system.
Most of my systems I don't even have BOINC Manager running. Since I am accessing the systems remotely when I need to do anything via boinccmd.

As far as shutting the system down you can do that remotely via a windows command line option. Open a command line prompt and type shutdown /? to get the full help instructions.

tbret or anybody

Team Viewer seems cheap and easy. What is this about push the power button less than 4 seconds? Wouldn't you just shutdown over Team Viewer?

--edit--
or use hals shutdown /s from the command prompt.

The default action for Windows is to start shutting down when the power button is pressed. This gives you a clean system shutdown.
If you hold the power button more than 4 seconds it is ATX spec to shut off the PSU. Which Windows will treat as an unexpected shutdown.

I might just try this with the new dell. I need to know how to do that. I always wondered about the headless one.

I'm to many years away from Linux now to go back to it. Too much like real work.

Could I just use a simple usb wireless adapter to connect to my netgear router for internet access? Would 300Mbps be good enough?

It would be fine for SETI I used one for a while.

It does however make logging on remotely a bit slow depending of course how close the PC will be to the router.

It will work.

It is Free as the page title say (unless you are a corporation/business):
"TeamViewer - Free Remote Control, Remote Access & Online Meetings"
http://www.teamviewer.com/

It also have (GUI) commands for remote reboot and shutdown
I sometimes use it to control from Bulgaria computer located in London

I run a bunch of Raspberry Pi's headless. They run Debian Linux and I just ssh into them to do stuff and BOINCtasks running on windows laptop to keep an eye on them.

For my windows machines I use a KVM and have a single monitor/keyboard between a bunch of them. I use BOINCtasks to keep an eye on them as well. With the windows boxes you get the windows updates and driver updates to apply but that's typically once a month.

I tried that KVM once but when I got around to unpacking the device about 2 years after I bought it I discovered it was totally incompatible with the equipment I was then using. So if you are buying one of those make sure you buy the appropriate device for your equipment.

Advice which applies in so many walks of life.....

For a KVM in particular, you will require a lot of cables. Sometimes they're included in the bundle, sometimes not. If they're not included, budget quite a lot extra for good-quality cables, especially if you're still using VGA (analog) video.

If I am using team viewer and I use a usb adapter of only300 Kbps does that cause a problem being too slow in downloading and uploading to the seti servers?

I'll bet your USB adapter is 300 Mbps. ;-) Evenso, there's some people still on 56k dialup that access this forum and crunch for SETI. 300Kbps would be a huge boost in performance for them, so I'm sure it would be enough for your system. :-)

I would guess that is several times faster than your internet connection. Unless you have GB fiber. In which case I don't want to know!

la la la la la la

At work I have 25 machines sharing a 100Mb pipe to the internet & that is more than enough bandwidth. The only issue I could see from using a wireless adapter would be if it acts weird and you can't access the machine. Which is an issue I have with one of my notebooks. It continues to have internet access fine, but won't talk to any other device on the network. I've chalked it up to being an older atheros wireless adapter.
