Need help finding a desktop hat runs Acad 2013/2014 properly

Hello,

 (Hope this is the right subforum, Mods please move if not :))

Currently i'm searching for a good budget PC since i want to start working in autocad at home, instead of always having to stay in school for Acad projects.

I'm a little low on cash so i'm looking for a used pc ( i couldn't care less, as long as it's from a legit website and offers guarantee).

Now i've done some research but in the end i just do not know enough to pick the right pc at this moment.

Now i've found this site offering a lot of pc's in a Dolphix case (guess the company behind the website build them theirself as i can't find any info on dolphix making full computers).

Here's the link: http://www.usedpc4sale.nl/en/category/renew-dolphix-586/ (dutch company, site also available in EN)

It's really a HUGE list of different stuff and i simply don't have the knowledge to pick the right setup.

Things like Processors, videocards, chipssets and what not  i simply know nothing about.

Hope you guys can help and pick the best out of that huge list. I'm aware that i will have to let them upgrade 2GB to 4GB (extra cost €19). 

What i'm planning on doing with it:

- Run Autocad 2014 properly and possible even Revit(Revit is not a must), Making 2D drawings 9/10 times of small buildings (maps, sections etc)

- Browse youtube and stuff and run spotify

- NO GAMING

- No downloading through torrents or other big files

- 80/160GB HDD will be enough

As you can see Autocad will by far be the heaviest thing to run, that's also te reason i don't want to overspend and buy some ridicilous next gen spacestation pc.

Budget is around €150 ( cap at €200 for now)

Looking forward to any responses and advice.

Kind Regards
