mining profitability - Bitcoin Stack Exchange

Private local pool with twelve ~10 year old computers (x-post from Bitcoin)

So, a quick background. I work for an after school non-profit. I'm the network administratotech person/miracle workeetc. I maintain the "network" and all of it's computers.
Since it's a non-profit and I'm still in school, I'm ridiculously underpaid, but it's a good company and they're flexible. However, I've had this recent idea to try making the industry minimum by using all of these "computer lab" PCs for bitcoin mining.
All of them (with the exception of two in the library) are about 5 to 10 years old. I have room for about 17 computers in this lab (possibly 20) and due to some law of the universe where elementary, middle school, and high school age kids somehow manage to break computers just by being near them, I have about 12 working. When I first got the job, most/all of them were full of malware and spyware, some running unlicensed copies of XP Pro so I have Ubuntu 10.04 on them. I'll be in the process of upgrading them over this week and next week.
The majority of the computers are these donated HP desktops that are dual-core P4s @ 2.5 GHz. The video cards are GeForce MX 440s (8x AGP). About four are Dell Optiplexes: single core P4s at 2.5 GHz with ATI Rage 128 Pros. The two library computers have integrated Intel GPUs and Pentium dual-core E200s.
Since I doubt I can do GPU mining, I was thinking about CPU mining. One core throughout the day from 11am - 8pm and from 8pm to 11am, these computers are working as hard as they can. I can write a few scripts and set up cron to do this for me. I was reading up on MMP (Multiminer Protocol) and have a computer in the "office" I can use as a server, then all the computers could run ufasoft and talk to the MMP server via JSON RPC unless there's a CPU miner that speaks MMP.
Has anyone done anything like this before? Does anyone have any advice? Is there a better way to do this? I spent most of yesterday reading up on bitcoin, bitcoin mining, etc. Still learning so if something I said doesn't add up, that's why.
P.S. Posting this year since I haven't gotten any attention from /Bitcoin.
tl;dr: what's the best way to set up a private pool of 12 average-end desktops in a LAN for cpu mining?

If the GPUs are based on the same architecture, it's usually enough to just look at the number of CUDA cores to see which one is better (but don't forget to look at the memory requirements for mining a certian cryptocurrency).
