Need some guidance

[Zorba2.17]

Hello everyone!

I have this PC: https://support.hp.com/us-en/product/HP-Omni-120-1200-Desktop-PC-series/5268240/model/5306873?jumpid=reg_r1002_usen_s-001_title_r0001

MOBO and Specs:https://support.hp.com/us-en/product/hp-omni-120-1200-desktop-pc-series/5268240/model/5306873/document/c02993109

I am looking forward to give her some more shelf life so as it could handle my python scripting needs; this could very well handle turbo cpp mainly DBMS and some school assignments with some crashes here and there.

My upgrading strategy:

I am upping the RAM to 6gig  (DDR3-1333) for sure.

there are 2 x  SATA 2.0  one goes to hdd(500gb) and other one is for optical drive 

So my choices are to either remove the hdd and throw in a new SSD or ditch the optical drive and give that port.

Lastly the cpu I am thinking about:https://ark.intel.com/content/www/us/en/ark/products/52209/intel-core-i5-2500-processor-6m-cache-up-to-3-70-ghz.html            if i could find one.

 

My questions to you are:

Where did I screw UP in planning?

Should I ditch her? and don't even bother ?

What would you do and recommend ?

Please do lend me some of your precious time!!

 

edit: please do consider it is an - All in one chassis so the cooling department is something I am totally uncertain about.
