Can you please put 3.3 on it. If not, please upgrade the default ssh/ssl 
unless you have already done so. 

With 3.3 you also get some of the other goodies including improved packet 
filtering.

The card? If it is a realtek based card - it will have very sucky 
performance. According to the lists I am on, the ether expresses  are
the entry level on OpenBSD systems for peole who care.

There are reports of OpenBSD machines running multiple gigabit ethernet 
cards without any problems - admittadly with more RAM and CPU, so any 
100Mb, Gb networking should scale happily from this base. The limiting 
factor will be the PCI bus. 

Of course - a non-PC solution is better! :)
