Just started ghetto mining, going after low end altcoins. BTCZ, HODL, what else?

I just started mining, have no real interest in bitcoin itself. Having a blast going after low difficulty coins just to collect.  Started with ZEN but was slow. Found BTCZ and bringing in (what I feel) is a bunch and seem to do well with Equihash. Just started serious HODLing today as well.

What else is out there thats generally worthless but easy to get? I'll move on to harder ones once I put together an actual GPU rig...fight now its just a 4820k running a 280X and GTX 950. Have HODL running on 2x i7s and a few i5s.  

Have a Sun X4600 4x octacore (or is it 8x quad?) AMD Opteron 3GHz and 128GB of DDR1 (its an old box) that I suspect might do real well with HODL? Or is the CPU architecture too outdated to be useful?   It has 6x PCIe slots too which may come in handy w/ risers, but if the CPUs can't do HODL in the background while the GPUs are running, I'm not using a 4U rackmount to power a bunch of junk video cards :/

Thanks in advance, and Hi!

You could try CRDS.CO for CPU mining.
