The individual Igus components seem like the obvious worst deal when there's an entire bag of them.
The video card is easily the trickiest part since it's only as good as the knowledge a team already has. Many school computers have the proper PCI-E slot, but don't have a power supply that can support it. So it could definitely be a miss for a team that doesn't check compatibility ahead of time. On the other hand, it could easily be a
MASSIVE win for teams who need another CAD machine and have an "almost there" computer donated to them. It also means the team should have some knowledge of CAD to make any use of it, considering that the team won't get it for another few weeks.
There are definitely some steals on there if a team has machining capability and can adapt to a part. 8 ABEC-rated metric bearings for 5 credits ?!

Or maybe they're a miss if there's a problem with reliability on the part, thus they're at fire-sale rates.
