So let's put some light on those WUs I started contribute with

I never participated before on any distributed computing project, but as I am virtually surrounded by computers, I was able to offer lot of CPU time from the moment I noticed the existence of FAH and LN team.
AMD FX-60 @ 2.8GHzMy oldest machine (in terms of both folding time and age) is good old dualcore Athlon64 representing socket939 in the best possible way. This little beast is dedicated to FAH, running SMP 24/7 and being like a living museum of computer history.
Intel i7-860 @ 3,4GHz, Radeon 5770This machine is dedicated mostly to video recording and processing, it is scheduled to wake/sleep often thus I can let it fold only few days per week, but with full power of 8thread SMP + GPU. Also it serves to me as a gateway to Pandora and entire world of Na’vi.
Intel i7-2600K @ 4GHz, GeForce GTX560tiMost powerful machine I have, whose awesome CPU I use often but only in short spikes, otherwise it happily folds 8thread SMP + GPU, almost 24/7. Although I am not a gamer, I bought that powerful Fermi GPU with FAH on my mind, like a some sort of "virtual gift" to the Stanford.
Intel C2D-E8400 @ 3,6GHz, GeForce 8800GTXLast but not least, as a backup/occasional-gaming/data-recovery/anything-you-throw-on-it box, otherwise it folds SMP + GPU.
All those beasts are loaded with fastest RAM that I could find for the appropriate platform, running Windows XP 32bit (stuck with them for compatibility and many other reasons), air-cooled, with high efficiency PSUs, thus giving me the best combination of reliability and performace I can have.
