A big thank you to the individuals who shared their computer component designs! ATwentyX is a collaboration between Karoly Negyesi of La Purd Ltd, Canada and features an E-ATX motherboard like the Asus Rampage V. SSI CEB will not fit. Main specifications include: 1) A rear 120mm fan for exhaust; 2) a top 140mm slim fan, such as the Prolimatech Ultra Sleek Vortex 1, also for exhaust; 3) 120mm tower coolers like the Scythe Fuma, Cryorig H7, and Thermalright TRUE Spirit 120M BW Rev.A (max height of 150mm); 4) SFX/SFX-L PSU with front intake and top exhaust; 5) accommodating any 12" or longer graphics card; 6) two 120/140mm side fans for intake; 7) a front 3.5" disk or two 2.5" disks (3.5" limits graphics card length to 11.5"); 8) bottom options include two 140mm slim fans, one fan and two 2.5" disks, or four 2.5" disks; 9) a compact size of 178*350*320 mm (approximately 178 x 35 x 32 cm), just under 20L; and 10) the case design allows for discreet cable management. The nCase M1's AC cable will be used, running along the top with the C14 connector above the 120mm fan. SFX PSUs will connect inside the case, while SFX-L cables exit to the top and connect outside. Both types of PSUs will have a consistent height due to their placement. SFX PSUs will be secured using two L pieces at the front, while SFX-L will be screwed directly to the top with the grille removed.
