I've used ebuyer for many years. Have no real complaints with products or service.
I have a Zoostorm PC from ebuyer. Good value, but a cheapo case. Basically does the job. The motherboard, disk, CPU are all well known brands. Memory is generic (but does the job). Cheap PSU (which was dodgy [on arrival] and so I replaced with a spare one as less hassle than sending the whole thing back).
