That should be peripheral.

Looks like a few components have been removed, but still looks peripheral.

Yeah one of the chips came off with the heatsinks. The one above it stayed on. Something else I need I fo on is when is it worth it to depopulate the board and in doing so is the board still sellable?

Extremely rarely. Not to most places as anything above shred rate.
Old telephone service equipment and mainframe/minicomputer implementation boards are often a target for depop. Board with >5-10 gold cap chips with full gold legs sitting in through pin sockets with a bit of lead solder.

Pre ultra Sun minicomputer servers can have dozens of flip chip gold cap ceramics. (Gold cap faces the board). Any old RISC server board or mini board for that matter is worth a look.

When the lowest price for a ceramic gold leg cpu is over $10 and the highest price for a full size board nearly half... sure! Depop makes sense!

On the flip side (pardon pun) messing up chip removal is a big no-no for chip prices. When a 5005 or RZ302 has just 200 pins and 77 pins, rsp, loosing a single pin... so be it. Loose 10 and the price drops. fast!

Also: Chris and boardsort as a whole are rather firm on depop rules. Remove anything your not told to remove here in the forum and it’s midgrade.
There are exceptions such as the case here above. Where a botched removal is clear rather than grabbing a high value chip or flatpack. Etc.

In cases of extreme component value or botched cleanups; I’ll help the poster in a review of what can be removed, or where the board is now.

However: If a post is made of dozens of different boards asking what can I harvest the answer will be nothing.
I’ll help walk through mistakes and obviously some boards simply demand depop by their existence. If you have a dozen gold caps on a small light board, all having gold pins and all being in TPS, sure! Post a photo and let’s discuss.
Just be reasonable. Posting a photo of a zapped ryzen board and asking which controllers can be removed isn’t a good idea.

Peripheral.
You’re missing a controller. Looks like was dual ASICs.
The UI chip was clearly never installed. Nor the second ATA port. You’re missing a small copper resistor stack but that doesn’t hurt. There’s some damage to the BNCs but my guess is there was a heavy shield over them. The nickel contacts are intact so no issue there either.
Looks like a botched heatsink removal alone (and some abuse over time).
