Seven as of yesterday (see sig), with another soon to be bought. I built a rig out of spare parts yesterday, but have no need for it whatsoever ... it was more or less to show some young friends how to build A PC. I have a lappy that usta be in my sig but I was cleaning the sig rigs up when I accidentally deleted that one.
I'm planning on buying an HP MediaServer 470 within the month, so that makes eight, but I really do want to sell off two of the PCs. None are even remotely close to stock, so its hard finding a general usage buyer that wants to pay extra for a good video card when Dell will sell them a PC for $400.
Yesterdays build was an e2180 rig with 2 320gb HDs to try out dual boot, and I had an offer on it today already, but there's no way in Hell I am selling a dual boot (XP, Vista Ult.) to be used as a family PC when I know I will be called within a month to fix something that the kids hosed on it.
Edit: There are more in the garage, but since they aren't hooked up to any monitor or KVM, I won't count them. The wife is on my case about tossing a few, so its a firesale around my house lately. I should just set up a fruit stand out front with a sign saying 'Free PC with every fruit purchase'.
