I have for sale my used Asus M2N-E motherboard with 4GB DDR2 and AMD Athlon 64 X2 4200+ CPU with heatsink/fan. I just tested it out by installing Windows 2000 Pro, then running a 3 pass memory test with Memtest86, and it is running great. This was in my main computer some years ago, and it was always very stable and reliable. I guarantee the motherboard to be in great running condition with no problems.
The CPU fan is barely audible when running.
This motherboard has the latest Bios for it, which is v5001
