importance of wlan internal antenna size and length

I'm installing a mini PCI WLAN card (802.11n/g) and antenna inside of a small form-factor PC. The enclosure is fully insulated with only two small slots in which to mount the tabs at the end of the WLAN internal antennas.

I can easily route the excess antenna cable inside the enclosure, though it would be nice to shorten these to the minimum length.

More importantly, the tabs at the ends of the antenna are too large to fit properly in the slots meant to receive them.

Is there any functional harm in:
1. shortening the antenna cables - I would guess not as they're inside of an insulated case anyway, and
2. can the tabs at the ends of the cables be trimmed slightly to fit the enclosure better without affecting their ability to properly TX/RX?

Thanks in advance,
Adam

For reference - the antennas I'm using:
