Good enough and very well priced
Ordered one for a friends gaming PC, the layout is a bit weird and required me to use some dupont cables as extension for the front panel connections, it also needed a right angle SATA as the SATA ports are far too close to the GPU, and we had to wire the fans drictly to the PSU due to the stupid 5 pin Dell fan connectors other then that everything works fine and being a business motherboard it is bound to have great reliability at a far cheaper price then any gaming focused LGA 1151 motherboard, if you can look past it's flaws then for the pice it is hard to go wrong. I just ordered one as an upgrade for my ageing LGA 775 home server.Verified purchase: YesCondition: Pre-owned

great upgradable motherboard
good motherboard, works good and not to shabby on the upgrading part. I would say, the heat sink for the mobo gpu could not get on to itVerified purchase: YesCondition: Pre-owned
