How much would it cost to cool my computers that generate 8800 BTU's with A/C and what is the cheapest way?

I have an an interior room in my house with no exterior walls. The central A/C for the house cools it just fine now. I am moving my in-home office with all my computer equipment (6 PC's, each with a monitor, UPS's and router's) that I've calculated generate 8800 BTU's, to that room.
Right now, my office is in another, larger room (300sqft) and it is on it's own zone of the house's central A/C with extra vents and it cools off just fine. I am trying to figure out the best and most economical way to cool the in-home office in the new room. I am considering 2 choices:
1. is to have an HVAC company re-route the extra vents to the smaller room.
2. is to buy a portable A/C unit and vent it to the attic.
I live in NC so there can be considerable heat here. Our utility rate is 9.6c/KW.
So, on a monthly basis, how much would it cost to cool the computers with a Portable A/C unit? How much would it (does it) cost to cool the computers with the central A/C?
