I unplugged the motherboard of a prebuilt pc (lenovo thinkcentre e73) and put in a mobo with a different cpu. the problem is that the cables are not matching with the mobo, and i read now that oem computers are impossible to upgrade, is this true or can i take a chance at sending my pc to a technician and risk wasting money on service charges?
 
Can you provide the details of the new motherboard and CPU? Brand, model name and number, etc.

I think that E73 was introduced in 2013. Quite old technology.

Why did you change boards? Had the old one failed completely?

I'd be skeptical it would be worthwhile to attempt the upgrade, but if you are indifferent to the cost, who knows?

you will not even recognize the brand but here is a online store link of the mobo: https://cshop.co.za/products/tbit-h61-motherboard-lga1155-ddr3

and the CPU is an i7-3770 (old one was i3-4160) (technically an upgrade albeit an older generation.) I changed boards for the reason being the i7 is faster but wouldn't fit the original mobo, as the CPU sockets are not the same. I fitted everything in the case. thanks for replying.

What model motherboard did you use?
You probably have to change PSU also.

Lenovo thinkcentre e73 uses proprietary PSU power connectors on motherboard.
I changed the old 180w psu to a 500w psu.
In the lenovo, there were just 2 places the old psu were connected to the mobo: the 24pin mainboard and the 4 pin CPU.
Now with the new psu and mobo, i have done the same thing, the 24pin and the 4pin. thanks for the reply.

Then I don't understand, what cables are not matching.
Show some photos.

Oh, ok. I get it.
You have proprietary cables from Lenovo case and don't know, where to connect them.

This is a tough ask. Essentially you'd have to find pinouts for all Lenovo proprietary cables, rewire them and attach appropriate standard connectors.

It's easier to get a new standard pc case and avoid all that rewiring mess.

i could never, would it be too much to ask an IT technician to do that? is it a task that would take way more than a few hours to finish?
