Hi all PC masters, I am planning to buy to laptop and sell of my current desktop which had been quite old and I had tried to look for information regarding the price of my PC but it is too hard to make a conclusion on how much it is worth so I would like to ask for masters help to determine its value. Thank you so much in advances for the answers

CPU: Intel I5-3570
Motherboard: Asus P8Z77-M
GPU: Aero GTX 1050 ti 4g
Power Supply: Aerocool AF-650
Memory: 8gb ram

Storage:
1-250gb hdd
1-465gb hdd
1-50gb hdd

Fans: 3
Mouse: Razer abyssus essential
Keyboard: Razer deathstalker essential 2014
Case: Cooler Master K-280
Monitor: Acer S230HL

Conditions:
Overall Conditions: 7/10(I think)
There is dust inside the pc as it has been used for a long time, i guess around 5 years like this? Not too sure as I get it from my brother when he bought a new laptop

Accidents:
1. Mouse had once dropped before and disassembled but still working after putting it back together(No problem encountered until now)
2. Monitor have a line which is from top to the bottom which is very thin, thinner than the width of a normal ruler and it is placed quite near to the center(around placing at 70% starting from left)
3. There's 1 time I am unable to boot up the system where the monitor does not shows anything and eventually I removed the GPU and click on power button and it seems to be back to working again(Maybe it some electric problem?), after that the pc working fine and smooth smooth

Expectation: I was hoping to get around 1200 from this to be use to upgrade my laptop later on. I know that it is more value to get either a new desktop or upgrading current desktop but I am more into the laptop.
Thats it for the information, hoping to get an idea on how it will be priced by the master. Thanks again in advance!!!

Here shows the monitor line I mention about, it is placed at the Windows logo there
