Just a quick heads up,
We bought a load of PC's from SCL Online (since been taken over), They have had various problems, the most serious is Capacitors blowing on the MSI 945gcm7 motherboards.
No warranty , so now I'm looking at having to solder new capacitors onto the motherboards. They are 1000uf 16V (replaced with 25v) and are £1.20 on ebay for 10.
If you have these boards, its wise to check them.
