I needed to install an extra Ethernet card on my machine at work. The process of getting it from the IT department was fairly easy, but the damn things didn't have the small screws you need, in order for the card to not hang on the PCI-E port...

Turns out finding that kind of screws is way more annoying than the card itself. :/ I don't get why they were not included, if they are essential for the operation of the card...
