If you have it
then you would have to return the whole system under the warranty, whereas build it yourself and if something goes wrong you only return the faulty part and can still possibly use the system, depending on the faulty component. Buying local is great if you can, just makes it easier if things go wrong rather than relying on courier. unfortunately for me north of the border that isn't an option. The first pc i built in 2006 was from parts bought at ocuk, a couple of years later a maxtor hdd died. OCUK sorted the rma after a quick phone call and me sending it back i received replacement in a couple of weeksall under 1 tag
