As soon as I plugged in it, I got an error code. 3 red flashes followed by 4 fast white flashes. Upon googling the error code my best guess is a defective power supply or the entire unit is toast. Wont boot up or even post the bios. Extremally disappointing considering I also order the HDMI expansion card, a new NVME and 64gb of ram im going to have to return. Also, unit was listed as having WIFI but had no wifi expansion card. Sticker on the bottom says its the i5 model but was listen as an i7, cant even boot up to confirm I have the correct unit.
