Hello
I’m in the process of building DAW PC and I can tell you that 700.00 BP or $1,000.00 US wont buy you a lot , for $1,000.00 - we are talking entry level machine ,you have to double you budget to get middle shelf PC , and triple for a good studio worthy PC ,go to neweeg.com and check components prices I think UK components prices should be close to US prices
