Finally my desktop pc upgrade is complete. For the first time in my life I bought a used computer. Yes you got that right. I got myself a used Lenovo ThinkCentre out of a demo pool. Demo pool machines have been tested by customers (mainly large companies) for a few weeks or months already. Usually they are in excellent condition what I can tell about my little ThinkCentre as well. Looks like a brand new one.

So, even though it's not the latest model it is way more powerful than an up-to-date pc within that price range.

In the beginning an integrated intel graphics adapter with vga/'display port' output made things ugly. Luckily I could replace that kindergarden toy with a low profile nvidia GT220 PCIe graphics card which now accelerates KDE SC's Kwin window manager faster by the factor 12.5. Sorry, those intel drivers for Linux still really suck!
