Illegal items

In PC Simulator, normally you can only get items through the Daily Market, Print Expert, and Store.
However, there are a few items that are normally unobtainable.

Hidden, but not illegal items

You can go to the Silk Road website to buy these stuff:

PUOIO Phone

It's just a phone. An iPhone.

Super Glue

This item makes the bonding between the 2 components infinitely strong.
The only way you can remove them is to use the Remove Component tool.

Illegal items

Projector

An actual projector and it works as a display! All you have to do is to set this as the monitor for your PC. Click the Monitor tool, select the projector, select the case.

RTX4080Ti

This was originally going to be implemented as a normal item, but it was too big to fit into computers and thus was made an illegal item.
Plus, it gets a random score at benchmarks and mining.
BTW, no Ti variant of the 4080 exists.

RTX4080

A newly discovered illegal item.
It has the same texture, size and shape, and benchmark and wattage score as the RTX4080Ti.

Pillow

Just a pillow.

Cube

Just a transparent wireframe cube.

Crate_Table

It was probably supposed to be the item that spawned when you bought the table, but it is now hidden and needs a save editor to spawn.

Illegal items that exist, but are broken

These items load successfully, but they do not render because the assets are missing in the final release.
Both items are only in beta versions 1 and 2 of PC Simulator 1.8.0.
And, they are showcased here.

Evaporator

It performs just like the evaporator of a liquid nitrogen overclock. You were supposed to put liquid nitrogen, through the liquid nitrogen tank below.

Liquid Nitrogen Tank

It holds the liquid nitrogen that you put in the evaporator.

Illegal items that are not discovered yet

Hydraulic press

Only shown in the 1.8.0 Trailer. Probably inserted into the code, recorded, then removed in the stable release.
