Will I be able to learn system administration on this machine ?

As the title suggests I want to educate myself and start learning about linux system administration. I got myself an old machine and I want to put CentOS on it. The specs are next:

Fujitsu Siemens Esprimo P2500

GPU Model (Graphic Card) : 661FX Processor Pentium 4, Cores: 1, CPU Speed: 3,060 MHz RAM : 1024 MB HDD: 80GB (currently, until I find one with at least 250GB)

I will be following this guide. https://www.reddit.com/r/linuxadmin/comments/2s924h/how_did_you_get_your_start/cnnw1ma

So what do you think ? Thanks in advance!
