Do you mean a bespoke build - i.e. you select your own components and want to know if OcUK do this service and at what cost?
If so, yes, and they charge between £50 -£130 (guestimate on recent forum chats) from a cheap basic build to expensive component builds (i.e. not custom water) - and is covered by 3 year warranty.
If you've finalised your component list take it to the Customer Service Forum - Pre-Sales Advice - and they should be able to give you a ballpark figure there.
