I expect their hardware will work with any modern distro.
Here is their download page
The Nforce2 chipset is wonderful, IMHO. If you would like to have four DIMMs instead of 3, Gigabyte has the GA 7N400-L
The memory is dual channel, so you are better off to get 2X256 instead of 1x512mB. 512mB is pretty cheap, so if you need 2gB, the GA board can use 4X512 while most others cannot. If you use Linux, you can select software RAID at installation and use two harddrives on two IDE cables. In RAID 1, this sytem will be able to read two files at once and stuff loads twice as fast. Neat, eh?
Industry seems to feel that 64 bit systems are wonderful, but they are too expensive now. This mobo and a 2500 or better will rock you for ten years and it has great performance for the price. I built a system using Nforce2 last year. Look for my report on the installation and performance:report.pdf
. From page 9 there is a performance report. With 7 users active simultaneously and running several servers, we used only 4% of the cpu! From page 11, there is information on the performance of the RAID array. It shows a factor of 2 speedup when two files are read at once. Since that report, I have started using JFS filesystems and 2.6 kernels for even better performance.
I reccommend Mandrake 10 Official
