So I have a guy that wants me to setup a mining rig for primecoin on 50 cpus in his office (he owns the place)

I'm pretty sure they are just basic computers, would it make more sense to join a pool still or just solo mine on all of them?

Depends what kind of CPUs they are. Some might be worth solo mining, others not.

I have a Primecoin cluster. Send me a PM if you want some help to setup. Include specs as well.

50 "Office" CPU's give him only ~5-10 XPM a day. Even if the electricity is free -  it's not worth it.

Each Cpu?

Assuming I have dual core 1.86ghz cpus?

Im pretty sure pool is better, if you connect only to slow clients, you may get higher stale ratio, worse than paying pool fee

How can I determine my expected prime generation from my primes per second number?

You can run a two to three days test run to see what can possibly be made when averaged out.

300 XPM per month for free would seem worth it to me.

How did you come up with these numbers? Basically I have a guy that want to setup an operation that mines 1000 xpms a day and he's asking me what he needs to buy to get it setup.

Because I know how much is the profit TODAY from usual office computers. If you tell me what exactly processors installed, I will say the exact number of XPM/day.

That figure sounds about right. The dual core 1.86 may take a couple of months to get a block, which will be even worse when the difficulty crosses 10.

He 'owns' the place - does he also get free wlectricity? Otherwise he will just lose money, unless he holds onto them and beleives they will be worth a lot more in future. But then you can just buy them.

They are Dual core 1.86ghz cpus, can you also explain how you come up with that estimate?

If this is Intel Core 2 duo E6300 1.86ghz, than you will receive ~7-9 XPM/day from 50 CPU's.
There is no mining calculator for XPM. This estimate come from my personal statistics. I mine here: http://ypool.net

Ok, and if I wanted to maximize the abount of xpm/day a single CPU could produce, what sortof core processors should I be looking at? I7s?

I have a guy that wants to mine 1000s of these things a day. Cost and electricity is not an issue at all...I just need to give him some ballpark hardware stats.

i5 is better then i7 (4 cores have both processors, "virtual" cores of i7 bring in this task a little, but the price is much higher)
But the best CPU is FREE CPU (botnet). I think that buing hardware now is stupid idea (CPU and GPU mining)

I think it impossible. There are only about 14k XPMs available to be mined a day. You need serious mining power to get "1000s of these things a day". Are you sure he has so much funds and electricity to get.. say 10% of the network? BTW, if that would happen he would raise difficulty.
