Is it safe to spend £2500 with ebuyer.com? (And any suggestions for a pre built if not?)

I have to be honest I had never heard of ebuyer until today. Earlier I seen a deal someone posted from there website that for all included looked like a really powerful piece of kit ebuyer.com/112…als is that a respectable company and will all the parts arrive as advertised? I also noticed they are expecting the item to come back in stock on the 3rd of December and there is a bit saying Model of GPU may vary from that shown but specifications will be identical. So the whole thing worries me slightly. Is it safe to spend this amount of money on the site? Does anyone else have any suggestions for a good pre built in the 1000-2500 range the cheaper the better
