Building a long travel hardtail from scratch! Advice please?

Ive been looking for a long travel hardtail for a while. Ive come across the Cove Stiffee FR frame (£579) and its exactly the type of bike im looking for. However I dont have a clue how much it will cost to build it up into a decent "hardcore hardtail". I thinking of some marzocci 55 forks. The rest of the spec doesnt have to be top of the range but im looking for components that ill be able to take a good thrashing. Anyone have any idea how much itll cost to build this frame up into a decent bike?

Don't know if it's quite what you're after but I've seen some good reviews and at this price it's a bargain.

The starting point was a Kinesis Maxlight frame followed by an LBS deal on a Marzocchi MX Pro fork and and just went on from then.
There's nothing like the feeling of hitting the trails on a bike that you have built yourself
