If you have a fat ps2, buy a Network Adaptor for it, got mine for £20 on ebay. Then I say buy Swap Magic, create a MC exploit CD with hdloader as one of the lefs, burn it and install. After that just copy games to the hdd. Also if you need to update the exploit you can create an iso and then also put that onto the hdd and run from there instead of burning another cd. Also I've copied the swap magic disks to the hdd as well, so if i run out of space i can still use swap magic, also saves the dvd from getting more scratches when you take it out.
