Installation notes for CentOS 6.2 on my AMD Athlon64 X2 5000+. You can find more complete Howtos on the Net, so I won't repeat this here.
Download
Via one of the ftp mirrors. I downloaded the 32 bit live-CD. Burn, done.
Basic install
As with my previous Linux installations, I did not do an update but a complete reinstall. I just scraped the existing FC14 installation, keeping the home-directories and manually installed software.
CentOS refuses to install on an ext3 volume, and requires an ext4 partition. Moving an existing ext3 to ext4 is easy though:
tune2fs -O extents,uninit_bg,dir_index /dev/<your_ext3_partition> e2fsck -pf /dev/<your_ext3_partition>
Afterwards, the data is still there and in the right format.
Installation worked nice, setup was more or less OK except for one BIG FAT BUG:
The LiveCD somehow misses to advertise the fact, that the partition chosen for installation is completely wiped in the process, even if you do not format it.
This may be written in small print somewhere, but should appear in big, fat, red letters prior to pressing OK for the installation (which apparently did not happen). This is especially evil, because a conventional install does not wipe the partition.
Fortunately I had a backup.
Tweaking

Cyborg R.A.T. 5 mouse
Got a new mouse recently (the old one was unsatisfactory, despite being expensive), which turned out to have issues with Linux. Doh.
The X11 desktop did not recognize mouse clicks roughly 30% of the time.
This could be fixed by Googling as per [1] (basically add
pointer = 1 2 3 4 5 6 7 8 9 10 11 12 0 0 0
to your /etc/X11/Xmodmap).
