A few ideas for the Borg
Take out the need for life support and crew quarters, and have a borg control nexus that would act as a bridge and give a joint combat exp. bonus
Also IMO as the borg are a collective, give them their own research facilities that way they will research quicker (and possibly make a very strong opponent, well heres wishing anyway)
Also, should the borg have captains?
And maybe (dunno if this is already done) have their boarding parties double the strength of other races, that way the assilimation affect would kinda work
IMO Borg should also start wit an inf supply source, that way they will definitly be a huge threat, after all, all borg ships can substain themselves
Now as Im always Federation I would love to see the Borg made as the strongest race as IMO they are the strongest of all the ST races. This way if I happen to border next to Borg terriorty then I must have defenses or I would be doomed. I say this cos Im currently in game early on (Game Date 2416.4), got two races on my borders with whom Im at war with, and they have nvr attacked me, hell Ive only ever seen one Light Cruiser from one of them which my explorer class starship made mince pie of(anyone want a piece?), and I have it on highest diff. lol
And finally on the ideas for the borg
Change the ships classes, something I didnt like bout all the other ST mods was the fact of all the bloody cubes being used, the Borg have only 3 types of Cubes, Normal Cube, Tactical Cube and a Fusion Cube(In order of size, smallest to Bigest), oh and If I remember correctly from a ST game, the colony ship is actually pyramid shaped.
If you want I can give you all of the Borg class vessels, and I should be able to get hold of some pics
And something I've just came to realize, I have just switched to Borg in my game to see how they are doing, well needless to say, they havent even designed any ships let alone built any
Now other then borg ideas
Have most of the general weapons for general races only and not for all (confusing when u have ur races weapons and general weapons at the same time)
As for the engines idea I posted earlier I think it should be left for now as it does work.
If you need any help (or maybe a new member to the team *hint hint*

) then just ask and I will gladly accept
Well that my 2 cents for now, holla at yer later
