Some parts I get seeded by Manufacturers yes. OCUK only give me stuff to test on site not on sub zero its the manufacturers I rely on for this.
Titans as yet no, I will be buying three at least. When a product is in such short supply I simply cant get it. So I must buy em. Later when the media have finished with the odd sample then I may be seeded them yes but again its not free.
I have to spend hours preparing and clocking them to showcase the product for the specific manufacturer on Hardware bot and on global and local forums. The cost of this is two £2000 cascades, a £1500 Single stage, a chiller, £200 a month electricity and now £100 a month in LN2 for starters not including time spent.
Users who think anything is free to me they are wrong. Manufacturers who seed product do so because they know you will showcase the hardware and put out the results for them. They also want there product to be associated with these results.
