If he wanted to spend a little more this is a good one to..
Or if he wants custom we can alway help him put one together...That little Swifty kit at that price is a pretty good value and its a great way to get someone into WC'ing with-out spending a fortune..It would be OK for light OC'ing....Now if he's wanting to use it for a quad-core or something I would for sure get something better....
If he's just going to be getting a CPU loop setup, you could get a pretty good custom setup for him for not much more:
7/16" ID Masterkleer Tubing - Cheap, but Ira-k swears by this stuff hehe
Dtek Fuzion - Popular block, can't dispute that it's awesome
DD-CPX1 12V Pump - That isn't the best pump around, but it would get the job done with a CPU only loop. You could alternatively spend twice as much now on a better pump like the MCP355 or MCP655, but that's up to you/your friend.
BIX 240 - This isn't a GTX or Thermochill PA, but it will get the job done and won't cost your friend his arm and/or leg in the process
With a couple high airflow fans, that comes to a total of around $170-180 with shipping. Or a tad bit more if you went with better pump.
Just an example though
I'm sure you know all this lucky
Edit: that also assumes he would use a t-line vs a res, which would cost more money to implement.
