Question about where to put them computer?

My 3 boys age 5 years old, recently have an interest in the computer. I'm starting to let them go on the computer games (the CD games). We have a couple options one where to put the computers and I can't decide. My husband has his computer upstairs in his office. Then downstairs we have 3 computers for them. There is 6 kids in the house, so don't worry they are the oldest kids in the house so they just get them for now, but soon they will be sharing. Anyway, since sometimes I pop in a game for them and have them play while I run around upstairs cleaning, caring for the other kids, cooking, etc and they play on the computer down there. Somebody told me that I should move them upstairs so they can be watched while they are on it. What do you think?

I'm really sorry my grammar seemed terrible n the question, but it is a typo and is supose to be "the"

If they are only playing CD games, then why would she need to watch them? They aren't online!

I personally would put them in the down stairs area, make it a fun play room, with book shelves, puzzles, board games, and the computers (that way there are other appealing things to do down there while they are playing, with three it could get messy)
We have eight computers in our house, two in the office that are adults only (although I sometimes let the girls use my laptop), the boys (four and six yo) have one in their room that plays a few CD games, one in my 13 yo room that he has free reign with, one in my ten yos room that only plays CD ROM games, and then three in the Learning room that get online for everyone, and again is parent controlled so that they cannot visit new websites without me typing in a password. Kind of tedious, since even different links say, at barbie dot com have to be approved, but it's safe. People are so afraid of life anymore.

We have so many because we're homeschooling seven kids and the computer is a great way to learn.

It should definitley be upstairs where they can be supervised. Computers can cause seizures. Even if you do not have epilepsy etc.

Move it when they get older and start having interests in like girls and stuff..

The computer should be in the kitchen.
