Unfortunately, the Lenovo product website only shows currently sold models. I could not find the H520. If you go to this page:

http/shop.lenovo.com/us/en/desktops/#facet-2=4&facet-5=2

After a minute or so an option to chat with someone will pop up. You may want to tell them your exact model and are looking for specifications (CPU's supported, RAM supported, Graphics cards supported, etc.) Maybe they have archived documents somewhere. My guess is you are going to be limited to third generation processors.

Maybe someone else here is more familiar with the H520 desktops and can help out.

What system/motherboard?

How do you expect to add a laptop GPU to a desktop PC?

 

[tonybrad7778]

What system/motherboard?

Its a windows 7. I don't really know what motherboard it is. I don't know how to check the type of motherboard

Try installing CPU-Z and see what board listed there.

The bios version is ESTK20A
And model is MAHBOY NO DPK. I've ran cpu-z and those are what where gotten @alexoiu

 

[alexoiu]

Yes, you should be able to replace it. What CPU having in mind?

I want a core i7 or core i5 and my desktop is a 32bit

 

[alexoiu]

Windows is 32 bit, I guess?

You need to back up a few steps.

1. Budget
2. Use
3. What you currently have

"about 30GB" = a full reinstall of your 32bit OS.

 

[tonybrad7778]

Yes it is 32 bit

 

[tonybrad7778]

My budget is about 450usd

 

[USAFRet]

My budget is about 450usd

OK, and?

 

[tonybrad7778]

Sorry for the down vote. Another mistake

If you have a 32 bit version of Windows (Operating System), the most RAM it will recognize is 4GB. Actually you will have less than that available, as some will be reserved for hardware.

 

[tonybrad7778]

Can i consider reinstalling windows to 64bit ?

 

[USAFRet]

Can i consider reinstalling windows to 64bit ?

Yes.
But you are considering new hardware as well. This may have an impact on the OS.

So....
1. What do you have now (full list, please)
2. What do you desire for the end state?

 

[tonybrad7778]

What i have is an intel pentium(r) 2cpus
2gb ram and an intel hd graphics card
And i want a core i5 or i7, at least 16gb ram
And a nvidia gt 860m graphics card
