i would just get some cheap own-brand (wallmart?) desktop stuff, as it'll be useless splashing out on expensive named ram for a (desktop)server system. Plus it might allow cash to load it up with 4GB rather than 2, which will be more useful....

I thought it was a server (well thats what its used for)

which ram do you think is best out of the Newegg selection above

That looks like a standard desktop pc, any memory that fits will work fine.

My sister is currently running this server and its quite low on Ram so ive been looking around and still not 100% sure if normal high speed desktop ram will work aswel as server ram which is so expensive.
