What's in the box:
What our customers say:
“Shipped immediately - in fact, it arrived the next day! Working great in my new server. Paired with an Intel Core i3-9300t. C246 chipset supports iGPU passthrough.”
“Perfect motherboard to shrink my full desktop that was acting as a server into a smaller itx NAS box.”
“Fast shipping! Perfect for my OPNsense build!”
“Exactly what I ordered. Seller was very helpful and communicative. Shipped basically instantly, faster than Amazon. I actually had to wait for the rest of the components to arrive before I could test this system. Overall a perfect experience, I will check back at this store before I buy anything new.”
“Working, testing at the moment with good sensations on my DIY NAS, I am very happy with my purchase.”
