My guess is with 10GiB or more you will have enough space to live on FreeBSD.
Hope that helps.

I'm planning to build a cheap (about 160-170€) system in about a month used in full experimental/testing mode and of course full-time lunatics tester since I have neglected lately my "alpha tester" duties here. I have an old 36GB raptor that I'm planning to use and I was going to make 2 partitions for windows xp and sidux (and any other linux distro through livecd), so we're going to have direct windows-linux comparisons. If we're to support freebsd maybe I could make a third partition for freebsd.

I have a CLI only install on USB I use for rescue and maintanence. It's fully functional and includes source code and ports. It occupies only 1,7GiB on that USB stick. I don't use FreeBSD with graphics at all so I can't say exactly how much more would be needed for X and a windowmanager but you'll probably need another GiB or so.

I still could not get AP workunit to download and therefore test the application >:(
pp:
If you only want to run AP on that machine you can do it like I do. First create an app_info.xml like below and make sure the binary is also present in the same directory.
--- Code: ---<app_info>
<app>
<name>astropulse_v505</name>
</app>
<file_info>
<name>ap_5.06r236_sse3_x86_64-pc-freebsd</name>
<executable/>
</file_info>
<app_version>
<app_name>astropulse_v505</app_name>
<version_num>506</version_num>
<file_ref>
<file_name>ap_5.06r236_sse3_x86_64-pc-freebsd</file_name>
<main_program/>
</file_ref>
</app_version>
</app_info>
--- End code ---
Then go to your SETI@Home preferences and add a separate preference for "school" assuming you don't use that profile for something else. Make the following adjustments:
--- Code: ---Run only the selected applications SETI@home Enhanced: no
Astropulse: no
Astropulse v5: no
If no work for selected applications is available, accept work from other applications? yes
--- End code ---
The last setting is the important one since that's what enables AP v505. Finally update the location of your FreeBSD computer to "school" and manually update the project once. Boinc should now download your new preferences and AP units should start downloading as soon as they're available.

A question for Urs here I guess... and I'm in deep water so bare with me if I completely misunderstand things here.
As I understand it, binutils in FreeBSD is from 2004 and has no knowledge of SSE3 and gcc from the base system can't generate SSE3 code because of this. Since I installed fftw from Ports I therefor assume it doesn't contain SSE3 code. Would your optimized Astropulse benefit from recompiling fftw with a newer version of gcc/binutils or is the speedup accomplished by the Astropulse application alone? Could it be statically linked with an optimized fftw to make things easier for users? There's an ongoing discussion on freebsd-questions@, debating the old toolchain in FreeBSD, and I've been following it for some time now trying to understand it as best as I can and its repercussions on the compiled code.
